<p>A dual polarized aperture coupled patch antenna system (10) having a back plate (14), a ground plane (16) and a patch plane (12). The patch plane has a conductive patch layer (24) on one side. The ground plane is positioned between the patch plane and the back plate, with the slot layer (28) confronting the patch layer and the microstrip feed network layer (30) confronting the back plate. The slot layer comprises a plurality of intersecting polarization slot pairs (34) etched into a conducting coating (32). The microstrip feed network layer comprises two feed lines (40 and 42) and a plurality of feed probes. Two feed probe members are coupled to each conductive patch (26) through one arm of each slot pair and one feed probe member is coupled to each conductive patch through each other slot pair. This arrangement provides dual polarization with effective cross polarization port-to-port isolation using only one microstrip feed network layer.</p> |
