Abstract
A dual polarization array that comprises horizontal polarization and vertical polarization arrays, combined with an efficient waveguide-fed standing wave feed array. The vertical polarization array comprises an offset, resonant, iris-fed, centered longitudinal-shunt-slot, standing wave array. The horizontal polarization array comprises a flared dipole fed by a longitudinal, shunt-slot, standing wave array. The waveguide-fed standing wave feed array is comprised of a plurality of waveguides that separately feed the horizontal polarization and vertical polarization arrays. The horizontal polarization array comprises a first plurality of radiating waveguides laterally disposed adjacent to each other that are separated by a first plurality of gaps. Each waveguide comprises a plurality of radiating flared dipoles disposed adjacent to a respective plurality of longitudinal radiating shunt slots. The vertical polarization array comprises a second plurality of radiating waveguides laterally disposed adjacent to each other that are separated by a second plurality of gaps. The second plurality of radiating waveguides are laterally offset from the first plurality of radiating waveguides. Each…
