Summary: | On one surface of a dielectric substrate having a thickness of one quarter of a signal wavelength, a ground electrode, and a strip line, one end thereof being connected to a high-frequency element via a wire, are formed. On the opposite surface thereof, which opposes a waveguide, a ground electrode is formed, a first electrode opening having a predetermined length and width is formed, opposite to a proximity of an open end of the strip line, and a second electrode opening is formed so that a center line of a width thereof is separated outward by one quarter of the signal wavelength from a conductor wall of the waveguide. Furthermore, via holes having a length of one quarter of the signal wavelength, electrically connecting the ground electrodes on either surface, are formed. The waveguide is disposed in proximity to the dielectric substrate so that a center of the first electrode opening coincides with that of the waveguide. |
