Array antennae are preferred over other type of antennae for the use in WiMAX mobile communication systems due to increasing demand for higher capacity, better coverage and higher transmission quality. Furthermore if the antennae array is adaptive in nature, it can maximize the efficiency of transceiver. This paper concentrates on three different microstrip antennae array configurations, namely uniform circular, uniform concentric and modified uniform concentric circular for 3.3 GHz frequency band for WiMAX application. The configurations of antennae arrays considered three parameters - half power beamwidth, number of side lobes and main lobe to side lobe ratio.
