POLARIZATION COUPLER

摘要

The present invention is provided with: a connector waveguide disposed in the axial direction of a circular waveguide to connect a rectangular waveguide having a short side with a length shorter than the inner diameter of the circular waveguide and the circular waveguide; a planar conductive wall formed across the connecting waveguide and the circular waveguide to divide the interior of the connector waveguide and the circular waveguide disposed parallel in relation to a direction extending along the long side of the rectangular waveguide; a first inclined surface formed on the inner wall of the connector waveguide in a position facing one surface of the conductive wall, the first inclined surface being inclined toward the conductive wall progressively in the direction toward the rectangular waveguide; a second inclined surface formed on the inner wall of the connector waveguide in a position facing the other surface of the conductive wall, the second inclined surface being inclined toward the conductive wall progressively in the direction toward the rectangular waveguide; and a coupling hole formed in the circular waveguide to retrieve one of the polarized waves separated by the conductive wall.
