Abstract
A new compact UWB microstrip line fed printed monopole antenna with two parasitic elements and partial ground plane is designed and fabricated. The proposed printed antenna is based on 1.5 mm FR4 substrate. The designed antenna radiator has the profile of letter A. The antenna return loss has been experimentally measured and simulated using both HFSS and CST MWS simulation softwares. The antenna impedance bandwidth shows UWB characteristics, where a bandwidth between 3.5 GHz up to a value higher than 20 GHz is achieved for |S 11| ≤ –10 dB. Comparison between measured and simulated results has been done, and good agreement has been achieved. Using such an antenna, many applications, including WiMAX, Wi-Fi, as well as UWB applications, would be available.
