ADAPTING APPARATUS, ELECTRONIC DEVICE, TERMINAL, AND ADAPTING APPARATUS MANUFACTURING METHOD

The present application relates to the field of radio frequency, and provides an adapting apparatus, an electronic device, a terminal, and an adapting apparatus manufacturing method, for example, an antenna structure of a sensor such as a radar, for use in solving the problem of connection between a microstrip line and a waveguide. The adapting apparatus provided in the present application comprises: a substrate, a coupling cavity, and a resonant cavity. The substrate is provided with a through groove passing through a first plate surface and a second plate surface, and a conductive layer is provided on the inner wall of the through groove; the coupling cavity is provided in the first plate surface of the substrate, and the coupling cavity is coupled to a first end of the through groove; a waveguide can be coupled to a second end of the through groove so that the coupling cavity can be coupled to the waveguide by means of the through groove; the resonant cavity is provided in the first plate surface of the su
