This paper presents a hybrid ring feeding dual-polarized patch antenna with high isolation in a wide working band. The proposed\nantenna consists of a circular radiating patch printed on the upper horizontal substrate, two pairs of Ã?â?? shaped strips printed on\ntwo vertical substrates, and a hybrid ring feeding network printed on the lower two horizontal substrates. The proposed antenna\nadopts Ã?â?? shape strips coupled feeding structure to achieve a wide operating band. Furthermore, a hybrid ring feeding structure\nwith high isolation in a wide bandwidth, which is firstly proposed, is applied as feeding network. When one port is excited, the\nfeeding network can realize twice the power cancellation.Thus, high ports isolation characteristics can be obtained. A prototype\nof the proposed antenna is fabricated and measured. Measured results show that the 10 dB reflection coefficient bandwidths of the\ntwo ports are both about 38.7%, with port isolation higher than 40 dB through most of the band, and the cross-polarizations are\nbelow âË?â??24 dB.
