Abstract

In this paper, a reconfigurable microstrip patch antenna with RF MEMS switch providing frequency reconfiguration is presented. This paper gives a brief account on the methodology of designing an antenna changing its frequency using RF MEMS switches. By implementing RF MEMS switch in the slot of a patch antenna achieves to make a change in the frequency of the antenna by switch action. The proposed design is analyzed in the frequency from 2 to 20 GHz. RF MEMS switch with serpentine cantilever beam is implemented with the design to make a switching in the frequency response of the antenna. The switch is designed with an isolation of 67.9 dB at 12 GHz. The insertion loss of the switch is 0.094 dB at 12 GHz. The antenna is designed to resonate at three different frequencies. The frequency reconfiguration of the antenna is analyzed by changing the state of the switch implemented in the antenna.
