Abstract
A waveguide antenna assembly includes a feedhorn having a cavity coupled to a waveguide polarizer. The waveguide polarizer includes a single aperture waveguide, septum-loaded waveguide, and a dual aperture waveguide coupled inline. The septum-loaded waveguide includes an internal septum and is formed from at least one internal wall having a varying thickness. The length of the circular feedhorn and the diameter of the feedhorn cavity can be adjusted with the length of the single aperture waveguide to maximize signal isolation between the orthogonal signal ports.
