Title:
DIELECTRIC TRANSMISSION LINE COUPLER, DIELECTRIC TRANSMISSION LINE COUPLING ASSEMBLY, AND NETWORK DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/187110
Kind Code:
A1
Abstract:
The present invention provides a dielectric transmission line coupler, comprising a circuit board, a microstrip line, a metal connector, and a coupling part. The circuit board comprises an insulated surface. The coupling part comprises a metal base and a resonator having a plurality of resonance points. The metal base is mounted on the surface, and comprises a resonant cavity and a channel communicating the resonant cavity with the exterior of the metal base. The resonator is located in the resonant cavity and fixed on the surface. Both the resonator and the resonant cavity are centrally symmetric structures and the centers coincide. The microstrip line is provided on the surface and linearly extends into the resonant cavity along the surface of the circuit board from the exterior of the metal base towards the center of the resonant cavity through the channel. The microstrip line and the resonator are arranged at an interval. The metal connector is mounted on the side of the circuit board facing away from the surface of the circuit board, and the cut-off frequency is lower than the operating frequency of electromagnetic waves in the resonant cavity. A dielectric transmission line is inserted in the metal connector, and the resonant cavity and the resonator pass through the circuit board and the metal connector and are coupled into the dielectric transmission line after performing mode conversion on the electromagnetic signal transmitted by the microstrip line.
