The patent US12046793B2 presents a novel connection structure for waveguides designed to transmit radio waves at millimeter wave frequencies and above. This structure features a rod-like dielectric surrounded by an outer conductor made from braided flat foil yarns, which possess conductivity. The connection involves a three-dimensional component that includes a conductive connection surface and an insertion hole. The design ensures that the connection enlarged portion of the outer conductor is electrically connected to the inner surface of the insertion hole, facilitating smooth electrical conduction at the corner of the connection. The claims also detail the alignment of waveguide paths within a specified error range, enhancing the efficiency of the connection.

Additionally, the patent outlines various configurations for the connection structure, including the use of conductive adhesive agents and molded interconnect devices. It describes a fixing member that secures the waveguide to the three-dimensional component, with an auxiliary pressing member to ensure a tight electrical connection. The design accommodates hollow square waveguides and includes features such as a gradually decreasing cross-sectional area of the rod-like dielectric, which aids in the connection process. Overall, the claims emphasize the innovative aspects of the waveguide connection structure, which aims to improve the performance and reliability of high-frequency wave transmission systems.
