Wireless communications need not only compact antennas but also which can radiate efficiently in more than one band. Now-a-days, antennas which are been operating at dual frequency are preferred. Generally Microstrip patch antennas which produce circular polarization can be used for this application. Circularly Polarized (CP) antennas can resolve the conflicts caused by the transmitter-to-receiver coordination. The main idea is to enhance the bandwidth of operation within a single-feed square patch truncated at its corner. The design involves four slits inserted into a square patch and a T-shape slot is inserted which produces circular polarization between 2.5GHz and 9GHz WiMAX applications range.
