Abstract

A design of frequency reconfigurable PIFA antenna is presented in this paper. The antenna consists of halves of three concentric rectangular patches. Five RF PIN diodes are inserted in proper locations for frequency reconfigurability. Four switching cases are considered. The first case (all switches are ON) results in a single-band operation at 850 MHz with impedance bandwidth of 12.9%. The second case (four switches are ON) results in dual-band operation at 810 MHz and 2.45 GHz with impedance bandwidths of 12% and 5.7%, respectively. Whereas the third case (two switches are ON) offers a dual-band operation, at 1.471 and 2.62 GHz with impedance bandwidth of 11.7% and 4.1%, respectively. Finally, the fourth case (all switches are OFF), the antenna radiates at 3.35 GHz with impedance bandwidth of 8.8%. The antenna covers several wireless communication applications as LTE, GSM 850, CDMA 850, Wi-Max, WLAN, Bluetooth, and Wi-Fi. The antenna is analysed using CST Microwave Studio, fabricated with photolithographic and scattering parameters are measured. Measurements and simulations show good agreement.
