Abstract: In an example embodiment, a waveguide device comprises: a first common waveguide; a polarizer section, the polarizer section including a conductive septum dividing the first common waveguide into a first divided waveguide portion and a second waveguide divided portion; a second waveguide coupled to the first divided waveguide portion of the polarizer section; a third waveguide coupled to the second divided waveguide portion of the polarizer section; and a dielectric insert. The dielectric insert includes a first dielectric portion partially filling the polarizer section. The conductive septum and the dielectric portion convert a signal between a polarized state in the first common waveguide and a first polarization component in the second waveguide and a second polarization component in the third waveguide.

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.
