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 square waveguide (1) has four ridges (6a, 6b, 7a, 7b). The cross section of the square waveguide (1) perpendicular to a waveguide axial direction is square. Inside the square waveguide (1), two rectangular waveguide terminals (4, 5) are formed by partitioning the inside along the waveguide axial direction. A septum phase plate (2) formed to get narrower stepwisely as its gets closer to a square waveguide terminal (3) opposite to the rectangular waveguide terminals (4, 5) is provided. A projecting portion (8) is provided on a part of a ridge (7b) formed on a ridge-side wall surface opposite to a wall surface, the septum phase plate (2) being joined to the wall surface in a part where the septum phase plate has largest width, the projecting portion (8) being larger than other parts of the ridge (7b) in a cross-sectional shape perpendicular to the waveguide axial direction.

摘要： A substrate is used as one tube wall of a hollow waveguide, the substrate including a strip line wired in an inner layer, a first ground surface formed on a front surface, and a second ground surface 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 can be obtained.
