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. Each of the slot area, the slot offset distance and the slot-to-slot separation distance is decreased successively for a succession of the plurality of slots.
