Abstract
A septumless polarizer is an OMT polarizer which is formed without a traditional thin septum which bridges the gap from the first assembly half to the second assembly half when the polarizer is split in the zero-current region of the rectangular waveguides (RHCP and LHCP ports). The septumless polarizer utilizes a dual-axis-stepped feature, which is included in one half of the polarizer only, creates the illusion of a traditional thin septum and actually improves performance. A close-proximity fastener scheme is enabled along with a fully encompassing pressure lip and contact pressure risks are mitigated.
