The frequency band 3.1-10.6 GHz released by FCC (Federal Communication Commission) as the commercial operation of UWB has been chosen as frequency range for this antenna based on coplanar waveguide (CPW) feed and circular shapes fulfilled according to fractal geometry. The proposed antenna is validated and designed by using an FR4 substrate with overall area of 34 x 43 mm2. The simulated results performed by CST-Microwave Studio and compared by ADS (Advanced Design System) show good matching input impedance with return loss less than -10 dB between 2.9 GHz and 11 GHz. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Fractal%20antenna" title="Fractal antenna">Fractal antenna</a>, <a href="https://publications.waset.org/abstracts/search?q=Fractal%20Geometry" title=" Fractal Geometry"> Fractal Geometry</a>, <a href="https://publications.waset.org/abstracts/search?q=CPW%20Feed" title=" CPW Feed"> CPW Feed</a>, <a href="https://publications.waset.org/abstracts/search?q=UWB" title=" UWB"> UWB</a>, <a href="https://publications.waset.org/abstracts/search?q=FCC" title=" FCC"> FCC</a> </p> <a href="https://publications.waset.org/abstracts/17070/design-of-a-novel-cpw-fed-fractal-antenna-for-uwb" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/17070.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">388</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">2</span> Compact Ultra-Wideband Printed Monopole Antenna with Inverted L-Shaped Slots for Data Communication and RF Energy Harvesting</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Adel%20Sennouni">Mohamed Adel Sennouni</a>, <a href="https://publications.waset.org/abstracts/search?q=Jamal%20Zbitou"> Jamal Zbitou</a>, <a href="https://publications.waset.org/abstracts/search?q=Benaissa%20Abboud"> Benaissa Abboud</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdelwahed%20Tribak"> Abdelwahed Tribak</a>, <a href="https://publications.waset.org/abstracts/search?q=Hamid%20Bennis"> Hamid Bennis</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Latrach"> Mohamed Latrach </a> </p> <p class="card-text"><strong>Abstract:</strong></p> A compact UWB planar antenna fed with a microstrip-line is proposed.

Each filter consists of two coupled stepped impedance resonators connected to microstrip feed lines. The coupled junction is utilized to connect the two BPFs to the antenna. This two band pass filters are designed and simulated to operate for the digital communication system (DCS) and Industrial Scientific and Medical (ISM) bands at 1.8 GHz and 2.45 GHz respectively. The proposed circuit presents good performances with an insertion loss lower than 2.3 dB and isolation between the two channels greater than 21 dB. The prototype of the optimized diplexer have been investigated numerically by using ADS Agilent and verified with CST microwave software. <p class="card-text"><strong>Keywords:</strong> <a
