This paper deals with analysis of performance parameters of RMSA, CMSA and NLMSA with respect to Bandwidth (BW), Voltage Standing Wave Ratio (VSWR) and Return Loss (RL) while achieving specific selective frequency and Bandwidth. Rectangular Microstrip Antenna (RMSA), Circular Microstrip Antenna (CMSA) and Non Linear Microstrip Antenna (NLMSA) has been designed with various dielectric materials like FR4 Glass Epoxy, ROGERS, and PAPER EPOXY and analyzed. The performance of these antennas was measured for 2.4 GHz frequency using co-axial feeding technique with High Frequency Structure Simulator (HFSS) and experimentally fabricated antennas are analyzed with Vector Network Analyzer (VNA). Optimization of patch dimensions is designed to get better performance parameters such as BW, VSWR and RL. The graphical comparison of all these performance parameters with respect to material and shape variation gives directions to select better Microstrip Antenna for any wireless application.
