Patent number: 11881607Abstract: 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.Type: GrantFiled: October 5, 2021Date of Patent: January 23, 2024Assignee: Lockheed Martin CorporationInventor: Jason Stewart Wrigley

Patent number: 11693166Abstract: 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.Type: GrantFiled: August 10, 2020Date of Patent: July 4, 2023Assignee: LOCKHEED MARTIN CORPORATIONInventor: Jason Stewart Wrigley

Patent number: 11646476Abstract: An asymmetric, broadband, compact and low-PIM orthomode transducer comprised of two parts is presented. Mating of the two parts results in the formation of a choke flange as well as a critical impedance step which suppresses unwanted modes and enables broadband matching of the junction between the two parts. Furthermore, a cruciform-quatrefoil waveguide type is utilized that transitions to an aperture. This waveguide configuration can lead to a lower overall part length, an improved reflection, and reduced manufacturing costs.Type: GrantFiled: June 9, 2021Date of Patent: May 9, 2023Assignee: Lockheed Martin CorporationInventor: Jason Stewart Wrigley
