In this antenna, a defect ground structure (DGS) and a U-shaped slot which is located on<br>the ground plane have been used to improve bandwidth. Antenna impedance matching has been achieved through creating two symmetric<br>incision on the microstrip feed line the antenna. Also rejecting Intruder frequency bands are omitted by two slots on the radiation patch, and<br>the performance of omitting rejecting frequency bands is controlled by putting two switches on the slots of radiation patch. Simulation<br>results show that the designed antenna is able to cover a frequency band 3.1-10.9 GHz (UWB) and does the performance of omitting<br>rejecting frequency bands in two frequency band 3.3-3.8 GHz (WiMAX) and 5.1-5.9 GHz (WLAN).</p>}, number={1}, journal={International Journal of Natural and Engineering Sciences}, author={NASRABADI, Esmail and REZAEI, Pejman}, year={2019}, month={Jun.}, pages={49–52} }
