Abstract
A dual polarized waveguide slot array includes a first waveguide and a second waveguide. The first waveguide includes major and minor cross-sectional axes and extends along a common longitudinal axis. The first waveguide further includes a plurality of slots disposed thereon for radiating or receiving signals of a first polarization. The second waveguide is coupled to the first waveguide, extending along the common longitudinal axis and having major and minor cross-sectional axes. The major cross-sectional axis of the second waveguide oriented substantially orthogonally to the cross-sectional axis of the first waveguide, and the second waveguide includes a plurality of slots disposed thereon for radiating or receiving signals of a second polarization substantially orthogonal to the first polarization.
