ABSTRACT:
A common aperture dual polarization array that comprises a vertical polarization antenna array that provides for vertical polarization, and horizontal polarization antenna array that provides for horizontal polarization. The vertical polarization antenna array is comprised of a flat plate shunt slot standing wave array that includes a plurality of sets of radiating slots configured in a staggered pattern that are laterally separated by an air gap. The horizontal polarization antenna array is comprised of a collinear array of radiating slots, a strip reflector, and a plurality of baffles that form a short backfire antenna array. The collinear slots are disposed orthogonal to the radiating slots of the vertical polarization antenna array. A feed network is coupled to the vertical polarization and horizontal polarization antenna arrays that comprises a centered collinear standing wave array of longitudinally aligned feed slots coupled to the vertical polarization antenna array, and the collinear array of feed slots coupled to the horizontal polarization antenna array. The plurality of baffles may be disposed adjacent to the horizontal polarization antenna array for increasing the effective aperture thereof. The feed network may comprise an offset resonant iris disposed in a rectangular waveguide, or a boxed stripline that comprises a meandered stripline. The vertical polarization antenna array may further comprise a plurality of waveguide shorts disposed in the gap between the sets of radiating slots of the vertical polarization antenna array.
