N2 - By introducing a meandering strip feeding structure, a patch antenna for wideband and low cross-polarization operation is proposed. The investigation shows that this feeding technique is suitable for both planar and curved grounding structures, where the impedance band widths (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 the experiments and a good agreement is observed.
