Antennas are important components in communication systems and play a role in transmitting and receiving signals. In modern wireless communication systems, multiband antenna has been playing a very important role for wireless service requirements. Now-a-days, antennas with multiband capabilities have been widely required in satellite and mobile communication systems to meet the growing system complexity. In this paper, a quad-band H-slot microstrip patch antenna for WiMAX application is presented. The radiation performance such as VSWR, return loss, radiation pattern and gain of the antenna are simulated using Ansoft HFSS and presented.
