Abstract: A ridged waveguide slot array includes a waveguide slot body having one or more walls that define a longitudinal axis of the waveguide slot body. The waveguide slot body includes a narrowed waveguide section having a plurality of slots disposed thereon which extend along the longitudinal axis, the waveguide slot body further characterized by a longitudinal center line. The waveguide slot body defines a waveguide aperture having a major dimension and a minor dimension, wherein the major dimension of the waveguide aperture is less than one-half wavelength of a signal intended for propagation therein. Each slot of the plurality of slots is characterized by a slot area, a slot offset distance that extends from the center of the slot to the longitudinal center line, and a slot-to-slot separation distance extending from the center of the slot to the center of an adjacent slot.

Abstract: A ridged waveguide slot array includes a waveguide slot body and a ridged waveguide section attached to the waveguide slot body. The waveguide slot body includes one or more walls having a plurality of slots disposed thereon. The ridged waveguide section includes two spaced apart opposing ridges disposed on the one or more walls of the waveguide slot body, and extends along the longitudinal axis of the waveguide slot body.

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.
