Microstrip patch antennas are strong candidates for use in many wireless communications applications. Microstrip patch antennas are also highly preferable for multiband as well as for the WiMAX application. In this paper, a multi-band H-slot microstrip patch antenna for Worldwide interoperability for Microwave Access (WiMAX) is presented. The radiation performance such as VSWR, return loss, radiation pattern and gain of the antenna are simulated using Ansoft HFSS, fabricated and then presented. This antenna has a simpler structure than other antennas designed for realizing multi-band characteristics which is just composed of a coaxial feed line, a substrate, and a ground plane.
