ABSTRACT
As the increasing demand for higher capacity, better coverage and higher transmission quality rises, array antennas are used in mobile communication systems. For WiMAX application different microstrip antenna array configurations such as uniform circular, uniform concentric and modified uniform concentric circular arrays are studied for 3.3 GHz frequency band. Based on the simulation results obtained it is shown that modified concentric circular array outperforms other array configurations in terms of half power beamwidth, number of side lobes and main lobe to side lobe ratio.
