Abstract:
A waveguide part (2) is closed at an end thereof by a short-circuit plane (2a) in which through holes (3-1 to 3-6) are formed. Radio wave absorbers (4-1 to 4-6) have been fed through the through holes (3-1 to 3-6) toward the inside of the waveguide part (2) and are in contact with the inner surfaces (3'-1 to 3'-6) of the through holes 3-1 to 3-6 for absorbing frequency signals that are non-reflection targets.
