Abstract

Patch antennas are popular and widely used in wireless communication systems. Many articles have been\npublished with regard to the design, fabrication of different types of patch antennas and arrays to suit the application\nrequirements, however very few articles have appeared on the impact of geometry and structure of Patch antennas like\ndimensions and thickness on the electrical performance of the patch antenna. The most commonly used material for\nfabrication of patch antennas is glass epoxy (FR4) laminate of 1.2mm and 1.6mm thickness which is readily available. In this\narticle, an analysis is made to find out the impact of FR4 laminate substrate thickness on the antenna performance parameters\nlike gain, return loss, bandwidth. The analysis is carried out by simulating the parameters for patch antennas operating at\n3GHz using FR4 material for different substrate thickness starting from 0.36mm to 3mm.
