Analysis of Frequency Reconfigurable Antenna for WLAN Application

Abstract

A new technique has been implemented for frequency reconfigurable antenna for WLAN application. Square ring slot is incorporated in ground plane for achieving the frequency reconfigurable antenna. The proposed antenna contains rectangular slots which are incorporated in square patch. RT duroid 5870 substrate is used for simulation purpose. Extensive simulations are performed in CADFEKO for antenna design and analysis. Copper slits are used as ideal switches in the rectangular slots to achieve the frequency reconfigurabilty. The improved gain has been achieved.
