WAVEGUIDE DEVICE WITH SEPTUM FEATURES

摘要

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.

1. 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; a polarizer section coupled between the common waveguide section and the divided waveguide section, the polarizer section comprising a central axis in a direction between the common waveguide section and the divided waveguide section, a first set of opposing sidewalls, a second set of opposing sidewalls, and a septum extending between the opposing sidewalls of the first set and forming a boundary between the first and second divided waveguides, the septum including:
first and second septum surfaces parallel to the central axis and extending between the opposing sidewalls of the first set; anda ridge that protrudes from at least one of the first or second septum surfaces, the ridge having a longitudinal axis extending in a direction of the central axis.
