Claim Text:
1. An apparatus comprising: a ground plane on a first side of a substrate; a first planar metallic antenna on a second side of the substrate; a second planar metallic antenna on the second side of the substrate, wherein the first planar metallic antenna and the second planar metallic antenna are configured to have orthogonal polarization; and a planar metallic parasitic element disposed between the first and second planar metallic antennas on the second side of the substrate and configured to provide electrical isolation between the first and second planar metallic antennas, wherein the planar metallic parasitic element is in the same plane as the first planar metallic antenna and the second planar metallic antenna, said same plane being parallel to the ground plane, the planar metallic parasitic element is electrically connected to the ground plane.
