Abstract

This paper presents the simulation results obtained with a circular patch antenna having an off centered narrow ring slit. With a particular location of ring slit near periphery of circular geometry, antenna resonates at two different frequencies which lie in the lower and upper band of Wi-Max communication adopted by IEEE 802.16. The efficiency and gain of antenna at one of these frequencies are better than those at other frequency while directivity is more or less same at two resonance frequencies. Experimental work is underway to test these simulation results.
