摘要：
In this paper, frequency reconfigurable antenna array is presented. Reconfigurability is achieved by using a pin diode as a switch in DGS (Defected Ground Structure) antenna. An antenna array without DGS is acting as reference antenna. Further array is designed with DGS using pin diode. Both of the designs were simulated using CST and they have operating frequency of 2.62GHz, 2.94GHz and 2.52GHz. The results show that, by using PIN diode with DGS, the gain and directivity of the antenna increased significantly. Gain improved from 4.6 dB to 10.6 dB at 2.62 GHz. Similarly directivity improved from 5.3 dBi to 10.4 dBi.
