Abstract: A partially dielectric loaded divided horn waveguide device for a dual-polarized antenna is described. The partially dielectric loaded divided horn waveguide device may include a polarizer, a waveguide horn, multiple individual waveguides dividing a horn port of the waveguide horn, and multiple dielectric elements partially filling the individual waveguides. The dielectric elements may include a dielectric member extending along a corresponding individual waveguide and one or more matching features for matching signal propagation between the partially dielectric loaded individual waveguides and free space. Various components of the partially dielectric loaded divided horn waveguide device may be tuned for enhanced signal propagation between the waveguide horn and the individual waveguides, and between the individual waveguides and free space.

Abstract: Methods, systems, and devices for a dual-polarized antenna array are described. An example antenna array may include a parallel plate polarizer that may include upper and lower plates. The antenna array may include stepped septums extending between the plates, each of the stepped septums having a first and second side surfaces, the stepped septums comprising first and second sets that are inverted relative to each other. The antenna array may include a first divided waveguides associated with a first polarization that may have a first set of opposing walls formed by first portions of the upper and lower plates and a second set of opposing walls. The antenna array may include second divided waveguides associated with a second polarization that may have a first set of opposing walls formed by second portions of the upper and lower plates and a second set of opposing walls.
