Abstract
A patch antenna is proposed for wideband and low cross-polarization operation by introducing a meandering strip feeding structure. The investigation shows that this feeding technique is suitable for both planar and curved grounding structures, where the impedance bandwidths (SWR < 2) of 24% and 32% can be obtained, respectively. In both cases, the cross-polarization levels are less than -20 dB in E- and H-planes across the passband. Also, symmetrical and stable radiation patterns are obtained. Simulation results are compared with experiments and good agreement is observed.
