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.

(canceled)
A waveguide device, comprising:
- a common waveguide section;
- a divided waveguide section having a first divided waveguide associated with a first basis polarization and a second divided waveguide associated with a second basis polarization;
- and
- a polarizer section coupled between the common waveguide section and the divided waveguide section, the polarizer section comprising a septum forming a boundary between the first and second divided waveguides, wherein the septum comprises:
- first and second septum surfaces;
- a plurality of stepped surfaces extending between the first and second stepped surfaces;
- and
- a ridge that protrudes from at least one of the first or second septum surface and is adjacent to at least one of the plurality of stepped surfaces.
