摘要： A high-frequency member assembly has two high-frequency members of which surfaces are attached to each other. Each member has a rectangular waveguide hole penetrating through the member and two choke grooves opened on the attaching surface. The waveguide holes communicate with each other to form a rectangular waveguide. An electromagnetic wave is transmitted through the waveguide. Each choke groove extends straight along a side of an end of the waveguide hole opened on the attaching surface to be away from the end of the waveguide hole by one quarter of the wavelength of the wave. The depth of each choke groove is equal to one quarter of the wavelength. The choke grooves of one member communicate with the choke grooves of the other member to substantially surround the waveguide with the choke grooves in an attaching area between the member.
