In this paper, a new design of a frequency reconfigurable microstrip antenna by using microstrip line feeding for UWB applications is
presented. The process of frequency band rejection is done through the slots on the radiation patch and ground plane of antenna. Also the
antenna bandwidth has been improved by using partial Defected Ground Structure (DGS). Then by putting two switches on the ground plane
slot, reconfigure ability is added to antenna. The antenna dimensions are 20×20 mm2 which is very compact. Simulation results show that
the designed antenna is able to cover the frequency range 3.1-10.9 GHz. Also shows a performance of frequency band rejection in the range
5.1–5.9 GHz which is related to WLAN systems.
