Design of reconfigurable antenna arrray for WLAN and WIMAX application

Abstract

In this paper we have presented the use of reconfigurable microstrip patch antenna elements in adaptive arrays. The combination of both reconfigurability and adaptivity in a single array is investigated. As the different standards have different requirements and use different frequency bands mainly around 2.4GHz to 5 GHz, the RF circuits and antennas designed for each system must be able to work at different frequency bands. For this purpose dual-band inset-fed reconfigurable antenna is designed and RF-MEMS switches are being used to switch between different frequency bands.
