Abstract:
1. A ridged waveguide slot array, comprising: a waveguide slot body having one or more walls that define a longitudinal axis of the waveguide slot body, the waveguide slot body comprising a plurality of slots disposed on the one or more walls; and a ridged waveguide section attached to the waveguide slot body, the ridged waveguide section comprising two spaced-apart opposing ridges disposed on the one or more walls of the waveguide slot body and extending along the longitudinal axis of the waveguide slot body, wherein 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, wherein the ridged waveguide section extends along a longitudinal center line of the waveguide slot body, wherein the ridged waveguide section comprises two ridges opposed along an axis of the minor dimension of the waveguide aperture, the two opposing ridges extending along the longitudinal axis of the ridged waveguide body internally therein, and wherein the waveguide body comprises two side surfaces and two broadside surfaces, and wherein the plurality of slots comprises a plurality of edge slots disposed on at least one of the side surfaces.
