Abstract
A waveguide device includes a first electrically conductive member having a first electrically conductive surface; a second electrically conductive member having a second electrically conductive surface which opposes the first electrically conductive surface; and a ridge-shaped waveguide member on the second electrically conductive member. The second electrically conductive member has a throughhole which splits the waveguide member into first and second ridges. The first and second ridges each have an electrically conductive end face, the end faces opposing each other via the throughhole. The opposing end faces and the throughhole together define a hollow waveguide. The hollow waveguide is connected to a first waveguide extending between the waveguide face of the first ridge and the first electrically conductive surface, and to a second waveguide extending between the waveguide face of the second ridge and the first electrically conductive surface.
