A low cross-polarization microstrip patch array antenna includes a microstrip patch array, an antenna substrate, a ground plane and a polarizer. The polarizer mounts over the array and includes a low dielectric spacer, a thin polarizer substrate mounted on the spacer and a plurality of uniformly spaced, thin, conductive strips on the polarizer substrate. The strips extend perpendicular to the direction of desired radiation and parallel to the direction of undesired radiation.
