Patent number: 11316239Abstract: The present invention features a waveguide transition. A waveguide transition is used to join two dissimilar segments of waveguide, in this case coplanar waveguide to rectangular waveguide, and vice-versa. Care taken during the design of the waveguide transition ensures that the reflection of electromagnetic waves, which may be traveling along the coplanar waveguide segment and toward the waveguide transition and subsequent rectangular waveguide segment, is minimized.Type: GrantFiled: April 10, 2020Date of Patent: April 26, 2022Assignee: ELECTRONIC DESIGN & DEVELOPMENT, CORP.Inventors: Sergio E.

Patent number: 8258897Abstract: Coupling between non-adjacent resonators and wave propagation through the waveguide structure in distributed EM filters are reduced by forming one or more holes in one or more of the resonators (planar or folded) and by passing a conductive structure through each hole normal to the resonator. The conductive structures (vertical vias or horizontal strips) are preferably grounded, either by direct connection or capacitive coupling to one or more ground planes or by creation of a virtual ground. The holes are spaced apart from the edges of the resonator so as to minimize any interference with the current and fields concentrated at the edges of each resonator. These conductive structures narrow the effective cavity width “aeff” for the waveguide as a whole and between non-adjacent resonators without affecting the cavity width “a” between adjacent resonators.Type: GrantFiled: March 19, 2010Date of Patent: September 4, 2012Assignee: Raytheon CompanyInventors: Kevin W.
