Abstract

The microstrip patch antenna is used for simulation to evaluate the characteristics of the antenna intended for Worldwide Interoperability for Microwave Access (WiMAX) application. The effect of the Defected Ground Structure (DGS) on the ground plane of the antenna is analyzed. Introducing the DGS structures will shift the resonant frequency to a lower order frequency and develop the return loss distinctiveness of the antenna. Flame Retardant FR-4 material is used for the fabrication of antenna and the conductive material copper is used for the patch and ground plane structures. Microstrip feed is used to excite the antenna for generating the desired resonant frequencies for the desired applications. The simulated outcomes are created by with High Frequency Structure Simulator (HFSS) software.
