Design & Simulation of Circular Microstrip Antenna With Defected Ground Structure (DGS) for WLAN Applications
In this paper, a circular microstrip patch antenna with Defected Ground Structure (DGS) has been analyzed and simulated for the WLAN applications. The proposed antennas have been simulated at 2.45 GHz frequency using co-axial feeding technique. Actually, the authors design two circular microstrip antennas i.e. conventional CMSA and CMSA with L-shape DGS. These antennas are simulated by the High Frequency Structure Simulator (HFSS). For study purpose they analyze the proposed antennas and simulated results compared on bandwidth, return loss, VSWR and radiation pattern. The resultant antenna with Lshape DGS has improved in parameter performance mostly in enhancement in Bandwidth (B.W.).
