Claims

[Scope of utility model registration request]

A housing having a cylindrical space inside and having openings at four places around the periphery; a cylindrical rotating part rotatably housed in the cylindrical space about its rotation axis; and four waveguides that are formed and selectively communicate with the four openings of the housing, and the four waveguides have tube axes on the diameter of the rotating part and ends thereof. first and second straight thin waveguides that are open on both sides in the diametrical direction and are orthogonal to each other in the plane direction; and symmetrically arranged on both sides of the first straight thin waveguide, and each end thereof a first section opening on a side surface of the rotating section at a location spaced apart by 45 degrees with respect to the first and second straight thin waveguides;
and a second 90° bent thin waveguide, and each of the four waveguides has its H plane disposed within a plane perpendicular to the rotation axis of the rotating section, and each The waveguides are arranged so as to intersect with each other in the direction of the rotation axis, and four step transformers are arranged in the opening provided in the housing, and the inner ends thereof communicate with the four waveguides. A waveguide type switch characterized in that these H planes are arranged in a plane perpendicular to the rotation axis of the rotating part.
