A PINdiode is used for reconfigurability. Centre frequencies are 1.38, 1.98, 2.89, 3.86, and 4.34 GHz in &amp;amp;ldquo;ON&amp;amp;rdquo; state of Diode and 1.56, 2.16, 2.88, 3.91 and 4.45 GHz in &amp;amp;ldquo;OFF&amp;amp;rdquo; state. Achieved maximum bandwidth is 18. The maximum gain of the proposed antenna is 2.7 dBi in &amp;amp;ldquo;ON&amp;amp;rdquo; state and 3.95 dBi in &amp;amp;ldquo;OFF&amp;amp;rdquo; state of the diode. The antenna is simulated, fabricated, and tested in the lab. Measured and simulated results are in good confirmation.</abstract> <index>Open Science Index 142, 2018</index> </article>
