Abstract: A waveguide architecture for a dual-polarized antenna including multiple antenna elements. Aspects are directed to dual-polarized antenna architectures where each antenna element includes a polarizer having an individual waveguide with dual-polarization signal propagation and divided waveguides associated with each basis polarization. The waveguide architecture may include unit cells having corporate waveguide networks associated with each basis polarization connecting each divided waveguide of the polarizers of each antenna element in the unit cell with a respective common waveguide. The waveguide networks may have waveguide elements located within the unit-cell boundary with a small or minimized inter-element distance. Thus, unit cells may be positioned adjacent to each other in a waveguide device assembly for a dual-polarized antenna array without increased inter-element distance between antenna elements of adjacent unit cells.

Abstract: In an example embodiment, an azimuth combiner comprises: a septum layer comprising a plurality of septum dividers; first and second housing layers attached to first and second sides of the septum layer; a linear array of ports on a first end of the combiner; wherein the first and second housing layers each comprise waveguide H-plane T-junctions; wherein the waveguide T-junctions can be configured to perform power dividing/combining; and wherein the septum layer evenly bisects each port of the linear array of ports. A stack of such azimuth combiners can form a two dimensional planar array of ports to which can be added a horn aperture layer, and a grid layer, to form a dual-polarized, dual-BFN, dual-band antenna array.
