In this paper, we have designed and analyzed the performance of reconfigurable antennas for wireless communication applications using RF MEMS switches over the frequency range of 0.5–7.5 GHz. The proposed reconfigurable antenna is designed with three identical shunt capacitive RF MEMS switches with AlN as a dielectric material. The RF MEMS switch used for the design of reconfigurable microstrip patch antenna is offering good performance i.e., actuation voltage is 4.5 V, the switching time is 45 µs. Based on the switching of the RF MEMS switches, the antenna is resonating at 0.9, 1.5, 3.5, 5.4 GHz. So, the antenna designed is capable to serve in multiple applications like RFID, GPS, WiMAX, and WLAN. |
