Abstract
A septum orthomode transducer polarizer (SPOL) is presented comprising sidewall ridges which increase bandwidth in the presence of draft angles for injection molding manufacturing techniques. A SPOL with sidewall ridges is able to accommodate draft angles for injection molding while creating greater modal separation within the SPOL and increasing the resultant bandwidth. A horn aperture may be included with the SPOL, and the combined structure may be injection molded as a single part to realize significant cost and mass reductions.
