Abstract
This disclosure provides a waveguide converter, which includes a first waveguide for propagating an electromagnetic wave, a second waveguide for being inputted the electromagnetic wave from the first waveguide and propagating the electromagnetic wave in a direction different from the propagating direction of the electromagnetic wave in the first waveguide, and an elongated-plate-shaped inner conductor arranged between the first waveguide and the second waveguide so that end portions of the inner conductor are exposed to the inside of the first waveguide and the second waveguide, respectively.
Claims20
A waveguide converter, comprising:
- a first waveguide configured to propagate an electromagnetic wave in a first direction;
- a second waveguide configured to receive, as an input, the electromagnetic wave from the first waveguide and configured to propagate the input electromagnetic wave in a second direction different from the first direction;
- an elongated-plate-shaped inner conductor arranged between the first waveguide and the second waveguide such that end portions of the inner conductor are exposed to an inside of the first waveguide and an inside of the second waveguide;
- and
- an insulator, including a cylindrical portion that fits onto at least a part of the second section, configured to electrically insulate the inner conductor from inside walls of the first waveguide and inside walls of the second waveguide;
- the inner conductor having
- a first section of a first width, the first section being exposed to the inside of the first waveguide,
- a second section of a second width, the second section being exposed to the inside of the second waveguide, and
- a convex portion in a part of the first section, and
- the first width being wider than the second width.
