Title:
COUPLING DEVICE, MANUFACTURING METHOD, WAVEGUIDE ANTENNA, RADAR, TERMINAL, AND PCB
Document Type and Number:
WIPO Patent Application WO/2022/218360
Kind Code:
A1
Abstract:
A coupling device, a manufacturing method, a waveguide antenna, a radar, a terminal, and a PCB. The coupling device comprises the PCB and a waveguide; the PCB comprises at least one switching area, each switching area is provided with a microstrip coupling patch, and each microstrip coupling patch is provided with a coupling gap; the PCB is also provided with a microstrip line, and each microstrip coupling patch is connected to the microstrip line; the waveguide has a waveguide cavity, and the waveguide cavity comprises a coupling port corresponding to the switching area; in the corresponding coupling port and the switching area, there is an overlapping area between the vertical projection of each coupling port on the PCB and the switching area, and the vertical projection of each coupling port on the PCB covers a microstrip coupling patch in the switching area. In the device, energy is coupled by means of the microstrip coupling patch, such that energy transmission between the PCB and the waveguide can be realized. Moreover, the coupling gap is provided in the microstrip coupling patch in the coupling device, such that the switching performance of the device can be improved, and the bandwidth can be expanded.
