Optimized Microstrip Patch Antenna (MPA) Array Design To Enhance Gain For S-Band Application

Abstract

The modern wireless communication system requires high gain, large bandwidth and minimal size antenna's which are capable to provide better performance. In this paper firstly optimized single element MPA is designed and then optimization of 1×2 array is achieved by using different spacing between array elements and finally 1×4 array is designed to achieve high gain. The impedance of corporate feed network of array is matched by using quarter wavelength transformer. The final antenna provides gain 14.45 dBi at resonant frequency 2.45 GHz .The antenna is designed on Rogers RT/duroid 5880 (tm) substrate by using Ansoft HFSS V.13 software. The antenna is suitable for S-band (especially for ISM) application
