Logashanmugam</a> </p> <p class="card-text"><strong>Abstract:</strong></p> An antenna is an assortment of linked devices that function together to transmit and receive radio waves as a single antenna. Antennas occur in a variety of sizes and forms, but the microstrip patch antenna outperforms other types in terms of effectiveness and prediction. These antennas are easy to generate with discreet benefits. Nevertheless, the antenna's effectiveness will be affected because of the patch's shape above a thick dielectric substrate. As a result, a double-pole rectangular microstrip antenna with nanofillers was suggested in this study. By employing nano-composite substances (Fumed Silica and Aluminum Oxide), which are composites of graphene with nanofillers, the physical characteristics of the microstrip antenna, that is, the elevation of the microstrip antenna substrate and the width of the patch microstrip antenna have been improved in this research. The surface conductivity of graphene may be modified to function at specific frequencies. In order to prepare for future wireless communication technologies, a microstrip patch antenna operating at 93 GHz resonant frequency is constructed and investigated. The goal of this study was to reduce VSWR and increase gain. The simulation yielded results for the gain and VSWR, which were 8.26 dBi and 1.01, respectively. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=graphene" title="graphene">graphene</a>, <a href="https://publications.waset.org/abstracts/search?q=microstrip%20patch%20antenna" title=" microstrip patch antenna"> microstrip patch antenna</a>, <a href="https://publications.waset.org/abstracts/search?q=substrate%20material" title=" substrate material"> substrate material</a>, <a href="https://publications.waset.org/abstracts/search?q=wireless%20communication" title=" wireless communication"> wireless communication</a>, <a href="https://publications.waset.org/abstracts/search?q=nanocomposite%20material" title=" nanocomposite material"> nanocomposite material</a> </p> <a href="https://publications.waset.org/abstracts/177575/optimizing-rectangular-microstrip-antenna-performance-with-nanofiller-integration" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/177575.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">111</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2682</span> Transmission Line Matrix (TLM) Modelling of Microstrip Circular Antenna</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Jugoslav%20Jokovic">Jugoslav Jokovic</a>, <a href="https://publications.waset.org/abstracts/search?q=Tijana%20Dimitrijevic"> Tijana Dimitrijevic</a>, <a href="https://publications.waset.org/abstracts/search?q=Nebojsa%20Doncov"> Nebojsa Doncov</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The goal of this paper is to investigate the possibilities and effectiveness of the TLM (Transmission Line Matrix) method for modelling of up-to-date microstrip antennas with circular geometry that have significant application in modern wireless communication systems. The coaxially fed microstrip antenna configurations with circular patch are analyzed by using the in-house 3DTLMcyl_cw solver based on computational electromagnetic TLM method adapted to the cylindrical grid and enhanced with the compact wire model. Opposed to the widely used rectangular TLM mesh, where a staircase approximation has to be used to describe curved boundaries, precise modelling of circular boundaries can be accomplished in the cylindrical grid irrespective of the mesh resolution. Using the compact wire model incorporated in cylindrical mesh, it is possible to model coaxial feed and include the influence of the real excitation in the antenna model. The conventional and inverted configuration of a coaxially fed circular patch antenna are considered, comparing the resonances obtained using TLM cylindrical model with results reached by the corresponding model in a rectangular grid as well as with experimental ones. Bearing in mind that accuracy of simulated results depends on a relevantly created model, besides structure geometry and dimensions, it is important to consider additional modelling issues, regarding appropriate mesh resolution and a relevant extension of a mesh around the considered structure that would provide convergence of the results. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=computational%20electromagnetic" title="computational electromagnetic">computational electromagnetic</a>, <a href="https://publications.waset.org/abstracts/search?q=coaxial%20feed" title=" coaxial feed"> coaxial feed</a>, <a href="https://publications.waset.org/abstracts/search?q=microstrip%20antenna" title=" microstrip antenna"> microstrip antenna</a>, <a href="https://publications.waset.org/abstracts/search?q=TLM%20modelling" title=" TLM modelling"> TLM modelling</a> </p> <a href="https://publications.waset.org/abstracts/50589/transmission-line-matrix-tlm-modelling-of-microstrip-circular-antenna" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/50589.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">280</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2681</span> Design of Broadband W-Slotted Microstrip Patch Antenna </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Neeraj%20G.%20Nahata">Neeraj G.

It has big disadvantage of narrow bandwidth. To improve the bandwidth a W-slot technique is used, it is efficient to enhance the bandwidth of antenna. The feeding point of antenna is very important for efficient operation, so coaxial feeding technique is applied to microstrip patch antenna for impedance matching. A broadband W-slot microstrip patch antenna is designed successfully which attains a bandwidth of 22.74% at 10dB return loss with centre frequency of 4.5GHz and also it attains maximum directivity 8.78dBi. It is designed by cutting a W-slot into the patch of antenna, because of this resonant slot, the antenna gives broad bandwidth. This antenna is best suitable for C-band frequency spectrum. The proposed antenna is designed and simulated using IE3D software. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=broadband" title="broadband">broadband</a>, <a href="https://publications.waset.org/abstracts/search?q=microstrip%20antenna" title=" microstrip antenna"> microstrip antenna</a>, <a href="https://publications.waset.org/abstracts/search?q=VSWR" title=" VSWR"> VSWR</a>, <a href="https://publications.waset.org/abstracts/search?q=W-slotted%20patch" title=" W-slotted patch"> W-slotted patch</a> </p> <a href="https://publications.waset.org/abstracts/25341/design-of-broadband-w-slotted-microstrip-patch-antenna" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/25341.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">320</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2680</span> Design of Broadband Power Divider for 3G and 4G Applications</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20M.%20El-Akhdar">A.

A microstrip interdigital filter is a great option for designing UWB filters. However, the presence of via holes in this structure creates difficulties in the fabrication procedure of the filter. Especially in the higher frequency band, any misalignment of the drilled via hole with the Microstrip stubs causes large errors in the measurement results compared to the desired results. Moreover, in this case (high-frequency designs), the line width of the stubs are very narrow, so highly precise small via holes are required to be implemented, which increases the cost of fabrication significantly. Also, in this case, there is a risk of having fabrication errors. To combat this issue, in this paper, a via-less UWB microstrip filter is proposed which is designed based on a modification of a conventional inter-digital bandpass filter. The novel approaches in this filter design are 1) replacement of each via hole with a quarter-wavelength open circuit stub to avoid the complexity of manufacturing, 2) using a bend structure to reduce the unwanted coupling effects and 3) minimising the size. Using the proposed structure, a UWB filter operating in the frequency band of 3.9-6.6 GHz (1-dB bandwidth) is designed and fabricated. The promising results of the simulation and measurement are presented in this paper. The selected substrate for these designs was Rogers RO4003 with a thickness of 20 mils. This is a common substrate in most of the industrial projects. The compact size of the proposed filter is highly beneficial for applications which require a very miniature size of hardware. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=band-pass%20filters" title="band-pass filters">band-pass filters</a>, <a href="https://publications.waset.org/abstracts/search?q=inter-digital%20filter" title=" inter-digital filter"> inter-digital filter</a>, <a href="https://publications.waset.org/abstracts/search?q=microstrip" title=" microstrip"> microstrip</a>, <a href="https://publications.waset.org/abstracts/search?q=via-less" title=" via-less"> via-less</a> </p> <a href="https://publications.waset.org/abstracts/102110/a-compact-via-less-ultra-wideband-microstrip-filter-by-utilizing-open-circuit-quarter-wavelength-stubs" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/102110.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">156</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2672</span> The Design and Analysis of a Novel Type High Gain Microstrip Patch Antenna System for the Satellite Communication</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shahid%20M.%20Ali">Shahid M.

In our approach, a polyphase filter is used to obtain the four 90° phase shift outputs to feed a square microstrip patch antenna. The antenna can be switched between four states of polarization in transmission as well as in receiving mode. Switches are interconnected with the polyphase filter network to produce left-hand circular polarization, right-hand circular polarization, horizontal linear polarization, and vertical linear polarization. Additional advantage of using polyphase filter is its filtering capability for cross polarization filtering in right-hand circular polarization and left-hand circular polarization operation.

The maximum gain at the resonant frequency of 2.45 and 3.5 GHz are 9.3 and 11.33 dBi, respectively. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=multi-slotted%20antenna" title="multi-slotted antenna">multi-slotted antenna</a>, <a href="https://publications.waset.org/abstracts/search?q=microstrip%20patch%20antenna" title=" microstrip patch antenna"> microstrip patch antenna</a>, <a href="https://publications.waset.org/abstracts/search?q=frequency%20selective%20surface" title=" frequency selective surface"> frequency selective surface</a>, <a href="https://publications.waset.org/abstracts/search?q=artificial%20magnetic%20conduction" title=" artificial magnetic conduction"> artificial magnetic conduction</a> </p> <a href="https://publications.waset.org/abstracts/12024/a-dual-band-microstrip-patch-antenna-for-wlan-and-wimax-applications" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/12024.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">380</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2668</span> Compact Microstrip Ultra-Wideband Bandstop Filter With Quasi-Elliptic Function Response</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hussein%20Shaman">Hussein Shaman</a>, <a href="https://publications.waset.org/abstracts/search?q=Faris%20Almansour"> Faris Almansour</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This paper proposes a modified optimum bandstop filter with ultra-wideband stopband.

The proposed bandstop filter is designed with unequal electrical lengths of the open-circuited stubs at the mid-stopband. Therefore, the filter can exhibit a quasi-elliptic function response that improves the selectivity and enhances the rejection bandwidth. The filter is designed to exhibit a fractional bandwidth of about 114% at a mid-stopband frequency of 3.0 GHz. The filter is successfully realized in theory, simulated, fabricated and measured. An excellent agreement is obtained between calculated, simulated and measured. The fabricated filter has a compact size with a low insertion loss in the passbands, high selectivity and good attenuation level inside the desired stopband <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=microstrip%20filter" title="microstrip filter">microstrip filter</a>, <a href="https://publications.waset.org/abstracts/search?q=bandstop%20filter" title=" bandstop filter"> bandstop filter</a>, <a href="https://publications.waset.org/abstracts/search?q=UWB%20filter" title=" UWB filter"> UWB filter</a>, <a href="https://publications.waset.org/abstracts/search?q=transmission%20line%20filter" title=" transmission line filter"> transmission line filter</a> </p> <a href="https://publications.waset.org/abstracts/151305/compact-microstrip-ultra-wideband-bandstop-filter-with-quasi-elliptic-function-response" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/151305.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">148</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2667</span> Study of Hydrocarbons Metering Issues in Algerian Fields under the New Law Context</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20Hadjadj">A.

Then, it would be easy to handle and to characterize complicated structures like T and Y junctions, truncated junctions, arbitrarily shaped junctions, cascading junctions and more generally planar multiport junctions. Another advantage of this method is that the edge line concept for arbitrary shape junctions operates with real parameters circuits. The validity of the method was further confirmed by comparing our results for various discontinuities (bend, filters) with those from HFSS as well as from other published sources. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=optimization" title="optimization">optimization</a>, <a href="https://publications.waset.org/abstracts/search?q=CAD%20analysis" title=" CAD analysis"> CAD analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=microwave%20circuits" title=" microwave circuits"> microwave circuits</a>, <a href="https://publications.waset.org/abstracts/search?q=S-parameters" title=" S-parameters"> S-parameters</a> </p> <a href="https://publications.waset.org/abstracts/25946/characteization-and-optimization-of-s-parameters-of-microwave-circuits" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/25946.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">454</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2663</span> Multiband Prefractal Microstrip Antenna for Wireless Applications</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yadwinder%20Kumar">Yadwinder Kumar</a>, <a href="https://publications.waset.org/abstracts/search?q=Priyanka%20Rani%20Amandeep%20Singh"> Priyanka Rani Amandeep Singh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper the design of a multiband pre-fractal micro strip antenna with proximity coupling feed is presented.

The main difficulty of the microstrip antenna is its narrow bandwidth. Several modern applications like satellite communications, remote sensing, and multi-function radar systems will find it useful if there is dual-band antenna operating from a single aperture. Some applications require covering both transmitting and receiving frequency bands which are spaced apart. Providing multiple antennas to handle multiple frequencies and polarizations becomes especially difficult if the available space is limited as with airborne platforms and submarine periscopes. Dual band operation can be realized from a single feed using slot loaded or stacked microstrip antenna or two separately fed antennas sharing a common aperture. The former design, when used in arrays, has certain limitations like complicated beam forming or diplexing network and difficulty to realize good radiation patterns at both the bands. The second technique provides more flexibility with separate feed system as beams in each frequency band can be controlled independently. Another desirable feature of a dual band antenna is easy adjustability of upper and lower frequency bands. This thesis presents investigation of a new dual-band antenna, which is a hybrid of microstrip and waveguide radiating elements. The low band radiator is a Shorted Annular Ring (SAR) microstrip antenna and the high band radiator is an aperture antenna. The hybrid antenna is realized by forming a waveguide radiator in the shorted region of the SAR microstrip antenna. It is shown that the upper to lower frequency ratio can be controlled by the proper choice of various dimensions and dielectric material. Operation in both linear and circular polarization is possible in either band. Moreover, both broadside and conical beams can be generated in either band from this antenna element. Finite Element Method based software, HFSS and Method of Moments based software, FEKO were employed to perform parametric studies of the proposed dual-band antenna. The antenna was not tested physically. Therefore, in most cases, both HFSS and FEKO were employed to corroborate the simulation results. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=FEKO" title="FEKO">FEKO</a>, <a href="https://publications.waset.org/abstracts/search?q=HFSS" title=" HFSS"> HFSS</a>, <a href="https://publications.waset.org/abstracts/search?q=dual%20band" title=" dual band"> dual band</a>, <a href="https://publications.waset.org/abstracts/search?q=shorted%20annular%20ring%20patch" title=" shorted annular ring patch"> shorted annular ring patch</a> </p> <a href="https://publications.waset.org/abstracts/12262/investigation-of-a-novel-dual-band-microstripwaveguide-hybrid-antenna-element" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/12262.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">402</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2659</span> New Design of a Broadband Microwave Zero Bias Power Limiter</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=K.%20Echchakhaoui">K.

Latrach</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper a new design of a broadband microwave power limiter is presented and validated into simulation by using ADS software (Advanced Design System) from Agilent technologies. The final circuit is built on microstrip lines by using identical Zero Bias Schottky diodes. The power limiter is designed by Associating 3 stages Schottky diodes. The obtained simulation results permit to validate this circuit with a threshold input power level of 0 dBm until a maximum input power of 30 dBm. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Limiter" title="Limiter">Limiter</a>, <a href="https://publications.waset.org/abstracts/search?q=microstrip" title=" microstrip"> microstrip</a>, <a href="https://publications.waset.org/abstracts/search?q=zero-biais" title=" zero-biais"> zero-biais</a>, <a href="https://publications.waset.org/abstracts/search?q=ADS" title=" ADS"> ADS</a> </p> <a href="https://publications.waset.org/abstracts/17068/new-design-of-a-broadband-microwave-zero-bias-power-limiter" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/17068.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">466</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">2658</span> Study of Superconducting Patch Printed on Electric-Magnetic Substrates Materials</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fortaki%20Tarek">Fortaki Tarek</a>, <a href="https://publications.waset.org/abstracts/search?q=S.%20Bedra"> S. Bedra</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In this paper, the effects of both uniaxial anisotropy in the substrate and high Tc superconducting patch on the resonant frequency, half-power bandwidth, and radiation patterns are investigated using an electric field integral equation and the spectral domain Green’s function. The analysis has been based on a full electromagnetic wave model with London’s equations and the Gorter-Casimir two-fluid model has been improved to investigate the resonant and radiation characteristics of high Tc superconducting rectangular microstrip patch in the case where the patch is printed on electric-magnetic uniaxially anisotropic substrate materials. The stationary phase technique has been used for computing the radiation electric field. The obtained results demonstrate a considerable improvement in the half-power bandwidth, of the rectangular microstrip patch, by using a superconductor patch instead of a perfect conductor one. Further results show that high Tc superconducting rectangular microstrip patch on the uniaxial substrate with properly selected electric and magnetic anisotropy ratios is more advantageous than the one on the isotropic substrate by exhibiting wider bandwidth and radiation characteristic. This behavior agrees with that discovered experimentally for superconducting patches on isotropic substrates. The calculated results have been compared with measured one available in the literature and excellent agreement has been found. <p class="card-text"><strong>Keywords:</strong> <a
