The rising importance of wireless communication and multimedia services increasing the efforts to the design and implementation of microstrip patch structures. A patch antenna is advantageous because of its low cost, small size, ease of fabrication, and can easily be integrated into many commercial transceiver systems. The performance of antenna is studied in terms of parameter like, Gain, Reflection Coefficient, VSWR, Impedance & Bandwidth of antenna.

INTRODUCTION Microstrip antenna elements radiate efficiently as devices on microstrip printed circuit boards. Microstrip patch antenna consists of a radiating patch on one side of a dielectric substrate with a continuous metal layer bonded to the opposite side of the substrate which forms a ground plane. The patch is generally made of conducting material such as copper or gold and can take any possible shape. A patch antenna is a narrowband, wide-beam antenna fabricated by photo etching the antenna element pattern in metal trace on the dielectric substrate [1]. The structure of Rectangular Microstrip Patch Antenna (RMSA) is as shown in fig.1. For a rectangular patch, the length L of the patch is usually 0.3333λo < L < 0.5 λo, where λo is the free-space wavelength. The patch is selected to be very thin such that t << λo (where t is the patch thickness). The height h of the dielectric substrate is usually 0.003λo ≤ h ≤ 0.05λo. The dielectric constant of the substrate (εr) is typically in the range 2.2 ≤ εr ≤ 12 [2]. Fig.1Structure of Rectangular Microstrip Patch Antenna (RMSA) Microstrip patch antennas radiate primarily because of the fringing fields between the patch edge and the ground plane. For good antenna performance, a thick dielectric substrate having a low dielectric constant is desirable since this
