摘要：
In this letter, we have proposed a dual-polarized planar circular slot antenna for wideband application. Two orthogonal polarizations were achieved by adopting different feeding mechanisms with high ports isolation. The horizontal polarization is excited by a meander-line coupled slot, and the vertical polarization is fed by a stepped monopole. The prototype of the proposed antenna has been built and tested. The proposed design obtained a fairly wide bandwidth (1.70-2.71 GHz) and a high isolation (>33 dB) over the entire band. The gain of the dual polarizations is also measured and discussed.
