Pattern Reconfigurable Antenna Using Non-uniform Serpentine Flexure Based RF-MEMS Switches

摘要

This paper presents the design and analysis of reconfigurable antenna using two circular microstrip patch antenna array with non-uniform RF-MEMS switches in L and S band. It consists of a pair of circular patch antenna with CPW on the same side of Si substrate. This reconfigurable antenna design consists of two RF-MEMS switches, to achieve pattern reconfigura-bility. Two RF-MEMS switches are used to electrically connect and disconnect the two circular radiating patches. The analysis of reconfigurable antenna using RF-MEMS switch is done using the simulation performed on Ansys HFSS electromagnetic simulator for the frequency range of 1 to 10 GHz. The reconfigurability of the antenna is analyzed for L to S band (2 to 4 GHz) in terms of return loss and radiation pattern. The proposed antenna shows the pattern reconfigurability at 2.3 GHz and 3.4 GHz.
