Abstract:
A waveguide circuit is provided, in which fixing a metal cover to a waveguide body with screws can prevent radiowave leakage suitably without any application of the conductive adhesive, solder and braze as a material for the radiowave leakage prevention. A metal plate is provided at the end of an aperture of a waveguide body in a radiowave traveling direction and overlaps with the end of a metal cover.
