A dual polarized antenna on a printed circuit board, the antenna comprises a plurality of orthogonally placed microstrip lines; a plurality of parasitic coupling strips; a feed network, the feed network being connected to the plurality of orthogonally displaced microstrip lines, at least some of the microstrip lines having selected ones of the plurality of parasitic coupling strips placed over at least a portion of the microstrip lines, the microstrip lines receiving electromagnetic signals; a bay, the bay covered by a thin layer of conductive material; and a radiating patch, the radiating patch displaced adjacent the bay by a plurality of standoffs, the electromagnetic signals coupling through the bay and exciting the radiating patch, the radiating patch producing first electromagnetic fields, the first electromagnetic fields exciting currents in the parasitic coupling strip, the currents creating second electromagnetic fields, the second electromagnetic fields canceling with the first electromagnetic fields.
