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.

Abstract: Methods, systems, and devices are described that include one or more septum features to improve performance of a waveguide device. In particular, the septum features may be utilized within a polarizer section of a polarizer device such as a septum polarizers. The septum feature(s) may be a ridge. When a plurality of septum features are employed, the location, size, shape and spacing may vary according to a particular design.

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.
