Title:
SIGNAL TRANSMISSION STRUCTURE, DIELECTRIC WAVEGUIDE CONNECTION STRUCTURE, VEHICLE AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/065918
Kind Code:
A1
Abstract:
The present application provides a signal transmission structure, a dielectric waveguide connection structure, a vehicle and an electronic device, which are used to reduce signal loss and improve signal transmission quality. The signal transmission structure comprises a connector, a metal waveguide and a dielectric waveguide, the connector comprising a first end and a second end that are oppositely arranged, the connector being provided with a first through hole that extends from the first end to the second end, and the first through hole having a metal inner wall; the metal waveguide has a second through hole, one end of the metal waveguide is connected to the first end of the connector, and the second through hole communicates with the first through hole; the dielectric waveguide comprises a core body and a cladding covered on the outer periphery of the core body; the dielectric waveguide has an insertion end that is inserted from the second end of the connector into the first through hole; at the insertion end of the dielectric waveguide, the core body has an extension section beyond the cladding, and an end portion of the extension section extends to the second through hole and is spaced apart from the inner wall of the second through hole; and the cross-sectional area of the end portion of the extension section gradually decreases in the direction from the second end to the first end.
