Abstract
A waveguide grating antenna apparatus includes a substrate layer, an asymmetric waveguide array layer upon the substrate layer, and a waveguide grating array layer formed above the asymmetric waveguide array layer. The waveguide array layer is composed of two forms of waveguide structures arranged in parallel. Each waveguide of the first form extends continuously, has a first width, and is laterally separated from each adjacent waveguide of the first form by a gap distance. Each waveguide of the second form extends parallel to and between adjacent waveguides of the first form within the first gap distance and is narrower than each of the first width and the gap distance. Pairs of the second form are closer to lateral sides of a first alternating set of the first form. The waveguide grating is composed of adjacent, separated elements extending axially along each waveguide of the first form.
