Abstract :
A wideband and dual polarization base station antenna used in IMT-Advanced system is designed and measured in this paper. Stacked patches are used to meet the requirement of broad return loss bandwidth for IMT-Advanced system (1710MH-2690MHz). The multilayer aperture coupled antenna provides wider impedance bandwidth over 49.5% (VSWR<;1.5). About 25dB isolation level between the two ports is achieved by using a novel feeding structure. The gain of the antenna is about 8.4 dB and the 3dB beam width is 65°±6°over the operating frequency range of the IMT-Advanced system. Experimental results are in good agreement with Simulations.
