Abstract
A waveguide unit (2) is closed at one end thereof by a short circuit plane (2a) provided with through holes (3-1 to 3-6). Radio wave absorbers (4-1 to 4-6) absorb a frequency signal being a non-reflective target in the state of being inserted through the through holes (3-1 to 3-6) toward the inside of the waveguide unit (2) and contacting inner surfaces (3′-1 to 3′-6) of the through holes (3-1 to 3-6).
Claims13
A waveguide non-reflective terminator, comprising:
- a waveguide unit whose one end is closed by a short circuit plane provided with a plurality of through holes;
- and
- a plurality of radio wave absorbers absorbing a frequency signal being a non-reflective target in a state of being inserted through the plurality of through holes toward an inside of the waveguide unit and contacting with inner surfaces of the plurality of through holes, respectively,
- wherein portions of the plurality of radio wave absorbers are exposed to an outside of the waveguide unit from the plurality of through holes and are larger than the plurality of through holes, respectively.
