Design and Comparative Analysis of 2.45 GHz Rectangular microstrip Patch Antenna

Abstract

Over the years, there has been plenty of development in communication systems which requires the development of low cost, minimum weight and low profile antennas that are efficient for maintaining great performance over a wide spectrum of frequency. The aim of this paper is to simulate, design and fabricate a rectangular microstrip patch antenna for analytical studies and global WLAN applications. The antenna is designed to operate at 2.45 GHz resonant frequency. FR-4 is used as a dielectric substrate with relative permittivity of 4.4 and thickness of 1.6 mm. The antenna proposed here have been modeled and simulated using High-Frequency Structure Simulator (HFSS) and MATLAB. The obtained results of antennas simulation indicates that the designed antenna fulfills the requirements and characteristics for different frequency bands. Also, results shows a good agreement with comparative analysis.
