Design and Simulation of 4×1 Corporate Feed Circular Microstrip Patch Array Antennas for Wireless Communication

Abstract

The purpose of this paper is to analysis the results obtained from the design and simulation of an array of circular microstrip patch elements. 4×1 corporate feed circular microstrip patch array antennas have been designed for three different dielectric constants of substrate with fixed substrate height. The proposed antenna is simulated using commercial General Electromagnetic Solver (GEMS) software version 7 and all the output parameters are presented in this paper. The effect of bandwidth due to change of dielectric constants have been investigated and bandwidth of each case is measured. The designed antennas are operated at the frequency range of 9.5 to 10 GHz and applicable for broadband wireless access, Wimax and radar applications.
