Beschreibung
Zusammenfassung:	A coupling apparatus and a manufacturing method, a waveguide antenna, a radar, a terminal, and a PCB are disclosed. The coupling apparatus includes a PCB and a waveguide. The PCB has at least one switching area, a microstrip coupling patch is disposed in each switching area, and each microstrip coupling patch is provided with a coupling gap. The PCB is further provided with a microstrip, and each microstrip coupling patch is connected to the microstrip. The waveguide has a waveguide cavity, and the waveguide cavity includes a coupling port corresponding to the switching area. For the corresponding coupling port and the switching area, an overlapping area exists between a 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 the microstrip coupling patch in the switching area. The apparatus couples energy by using the microstrip coupling patch, so that energy transmission between the PCB and the waveguide can be implemented. In addition, the microstrip coupling patch in the coupling apparatus is provided with the coupling gap, so that transfer performance of the apparatus can be improved and bandwidth can be expanded.
