摘要： 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).

摘要： A substrate (1) is used as one tube wall (12) of a hollow waveguide (11), the substrate (1) including a strip line (2) wired in an inner layer, a first ground surface (3) formed on a front surface, and a second ground surface (4) formed on a part of a back surface. As a result of such a configuration, a waveguide strip line transducer having the same dimension as the external dimension of the hollow waveguide (11) can be obtained.
