In this paper, simple Rectangular Microstrip Patch Antenna (RMPA) is designed and its performance parameters are compared with RMPA having defected ground plane. The antenna is simulated at 2.4GHz using CAD-FEKO simulation software. This paper mainly includes modification of antenna ground plane called as Defected Ground Structure (DGS). The parameters of antenna such as reflection coefficient, gain, Voltage Standing-Wave Ratio (VSWR) and band width, with and without Defected Ground Structure (DGS) are measured. This paper is to improve band width so that patch antenna is used for wide band applications and study effect of DGS on antenna parameters.
