A Circular Ring Slot Antenna (CRSA) with microstrip feeding technique is analyzed at 2.45GHz frequency. In order to suppress additional harmonics produced by the ring slot pattern in wide range nearly 3 to 8GHz, a Defected Ground Structure (DGS) is integrated into the CSRA. The proposed antenna is analyzed and simulated mainly for the wireless sensor network applications. This antenna is simulated by the High Frequency Structure Simulator (HFSS). Analyzing, the proposed antenna and simulated results on return loss, radiation pattern and gain.
