Abstract:
1. A waveguide coupler, comprising: waveguide terminals arranged in a rectangular shape and formed in a glass epoxy substrate and a ceramic substrate arranged opposite to each other, wherein each of said substrates includes a contact region which conducts electricity to a grounded conductor of said waveguide terminals, one said contact region being arranged to surround said waveguide terminals at a position opposite to the other said contact region when both said waveguide terminals are connected together, said substrates are joined together with a plurality of electrically conductive joint members arranged in an array shaped like a rectangle surrounding said waveguide terminals between said opposing contact regions, and said waveguide terminal of said ceramic substrate is formed by a plurality of hollow through holes arranged in a rectangular shape facing said waveguide terminal of said ceramic substrate inside the array of said plurality of electrically conductive joint members.
