This paper presents a new dual-polarized square waveguide antenna fed by a microstrip patch. The proposed antenna consists of a square waveguide, a square microstrip patch, two orthogonal coplanar waveguides feeding the patch by proximity coupling, and an air-filled cavity backing the patch. Wideband characteristics have been obtained by feeding the patch on the reverse side of the patch and by backing the patch with a thin rectangular cavity. An optimum design has been obtained from parametric analysis. The designed antenna operates at 35-37 GHz with reflection coefficient of less than -10 dB, port-to-port isolation of greater than 24 dB, gain of greater than 9.5 dBi, and boresight cross-polarization discrimination of greater than 28 dB.
