In this paper, various Defected Ground Structure (DGS) patterns are inserted in a ground plane of a conventional Rectangular MicroStrip patch Antenna (RMSA). The antenna is designed for 2.4GHz frequency. The performance of the antenna varies as the dimensions of DGS patterns are changed. The antenna is simulated by the software HFSS. HFSS is employed to analyze the proposed antenna and simulated results on return loss. The bandwidth varies as the DGS pattern becomes more complex, it increases with complexity. The parameters of antenna such as Return Loss, VSWR and band width, with DGS and without DGS are measured.
