Substrate Height and Dielectric Constant Dependent Performance Analysis of Circular Microstrip Patch Array Antennas for Broadband Wireless Access

Abstract

Corporate series feed circular microstrip patch array antennas have been designed for three different substrate heights and dielectric constants of substrate. Bandwidth and radiation pattern have been analyzed by using General Electromagnetic Solver (GEMS). Effect of bandwidth due to change of substrate height and dielectric constant have been investigated. Finally, bandwidth for each substrate height and dielectric constant are measured for selecting the optimal patch array antenna which is used for Broadband Wireless Access.
