A novel design of a microstrip patch antenna incorporated by two orthogonal L‐shaped switchable slots is proposed to achieve circular polarization. Two pin diodes are inserted into these L‐shaped slots and by making these two pin diodes ON and OFF the antenna can radiate with either right handed circular polarization or left handed circular polarization with wide bandwidth. This antenna can be used in unlicensed & licensed WiMAX (IEEE802.16a), future planetary missions and satellite link. © 2008 Wiley Periodicals, Inc.
