Design Simulation and Analysis of a Dual Band Microstrip Patch Antenna for GPS and WLAN Applications

Abstract

A microstrip patch antenna is a form of antenna that features a radiating patch on one side of a dielectric substrate and a ground plane on the other. It was invented in 1972 by Bob Munson. (However, Deschamps' prior work dates back to 1953.) Because of their low cost, low profile, and ease of manufacture in circuit boards, microstrip antennas have become an integral feature of today's wireless communication world. The Global Positioning System (GPS) and Wireless Local Area Network (WLAN) are two of the most widely used and crucial characteristics in today's generation. Because they are separate features, they take up more space in a device to use. The primary goal of this research is to create a dual-band microstrip patch antenna for GPS and WLAN applications. CST Microwave Studio was used to build and simulate the antenna, which runs at 1.5 Ghz for GPS applications and 2.4 Ghz for WLAN applications. This theta polarized microstrip patch antenna has gains of 6.82 dBi and reflection coefficients of - 30.99 dB (VSWR = 1.263) and -35.79 dB (VSWR = 1.03). Both frequencies have a combined efficiency of at least 70% and a directivity of more than 7.5dBi. Because of its dual-band quality and increased gain performance, this dual-resonance antenna may be simply integrated into communications systems
