Abstract
Design of a frequency reconfigurable patch antenna is proposed in this paper. The designed antenna is compact in size with overall dimension of 25 mm×25 mm on FR-4 substrate with a thickness of 1.6 mm. antenna covers 5 different frequency bands and operates on 4.80 GHz, 5.32 GHz, 6.01 GHz, 6.22 GHz, and 6.41 GHz. Frequency reconfigurability is achieved by PIN diodes. Two PIN diodes are used as switches to switch the frequency. Also the ground is modified with defected ground structure (DGS). Antenna is simulated and analyzed using HFSS software using FR-4 as substrate having thickness of 1.6 mm. Parameters such as S11, VSWR, gain and radiation patterns of antenna are analyzed and discussed in this paper. Designed antenna is useful for WLAN, Wi-Max, and C-band applications. This antenna having the advantage to be compact, easy to fabricate, and also it is not much complex.
