Design of 4 × 2 corporate feed microstrip patch antenna using inset feeding technique with defective ground plane structure

Abstract

Radar and satellite communication uses X-band antennas. Also, high gain and minimal size antennas are key requirements to latest wireless and satellite communication systems. The main parameters or constraints to the design of patch antennas include length and width of the antenna and substrate thickness and type. In this paper, the proposed 4 × 2 corporate feed microstrip patch antenna which is designed to operate at 10 GHz. It was found that the 4 × 2 patch antenna delivers a higher gain and return loss. The significant reduction in mutual coupling has been experimented using Defective Ground Plane (DGS). The paper introduces design of patch feed network using the high frequency structural simulator (HFSS) and the simulation results were compared with that of 4 × 1 patch antenna. The gain, return loss, and radiation pattern are analyzed and presented.
