Effects of different substrates on Rectangular Microstrip patch Antenna for S-band

In this paper, the performance of Rectangular Microstrip Antenna (RMSA) is analyzed by changing the substrate materials. RMSA is designed to operate for 3GHz resonant frequency for various substrate materials. A comparison has been done in terms of reflection coefficient, VSWR, gain, efficiency, radiation pattern and cost. The simulation analysis shows the maximum bandwidth of 82MHz when Polystyrene substrate is used. The Antenna is simulated using simulator CAD FEKO EM solution software (6.2 suite).
