Abstract
A waveguide grating antenna apparatus includes a substrate layer, a lower waveguide array layer upon the substrate, and an upper waveguide array layer positioned above the lower waveguide array layer. The lower waveguide array layer is composed of a plurality of first waveguides extending axially and a plurality of second waveguides extending axially and arranged in parallel and alternating in position with the plurality of first waveguides across the lower waveguide array layer. Each first waveguide is of a first maximum width. Each second waveguide is of a second maximum width narrower than the first maximum width and is spaced apart from each adjacent first waveguide. The upper waveguide array layer is composed of adjacent, separated elements extending axially along each first waveguide and each second waveguide.
