摘要：Wireless communications need not only compact antennas but also which can radiate efficiently in morethan one band. Now-a-days antennas which are been operating at dual frequency are preferred. Generally Microstrippatch antennas which produce circular polarization can be used for this application. Circularly polarized (CP) antennascan resolve the conflicts caused by the transmitter-to-receiver coordination. The main idea is to enhance the bandwidthof operation within a single-feed square patch truncated at its corner. The design involves four slits inserted into asquare patch and a T-shape slot is inserted which produces circular polarization between 2.5 GHz and 9 GHz WiMAXapplications range. This structure offers size reduction compared to other conventional CP antenna designs. Theparameters which are observed are return loss, VSWR, Radiation patterns at two different frequencies from 2.5GHzand 9 GHz.
