A dielectric plate is fixed inside a first waveguide, the inside of which is hollow, having a square opening at one end thereof, the dielectric plate is orthogonal to two parallel sides of the opening, a second waveguide having a square cross-section is connected to the other end of the first waveguide, and the dielectric plate is tilted by substantially 45° with respect to a pair of opposing internal wall surfaces of the second waveguide.
