Abstract: A complimentary split ring resonator (CSRR) defected ground structured Circular Patch Antenna is proposed for WiMAX applications. Rectangular slits are loaded on circular patch with CSRR on ground plane for better impedance matching and enhanced gain. The proposed antenna is designed using High Frequency Structural Simulator (HFSS) and Computer Simulation Technology (CST) simulation tools. The proposed rectangular slit loaded circular patch antenna resonates at 8.5GHz and 8.54 GHz frequencies for HFSS and CST simulator with return loss of -26.39dB and -33.8 dB respectively. The maximum gain is observed as 8.29dBi and 8.17dBi for both HFSS and CST simulators.
