    摘要： A waveguide unit including a vertically polarized waveguide, a horizontally polarized waveguide, and a waveguide type-polarized wave converter interposed between said waveguides. The waveguide type-polarized wave converter has a slit, the shape of which being combination of two quadrate parts and a connecting part for connecting the two quadrate parts.

    摘要： A nonreflective waveguide terminator includes a waveguide portion and an electromagnetic wave absorber. The portion has a rectangular opening in a plane perpendicular to a radio-wave propagation direction. The portion has one open end in the direction and the other end closed by a terminating metal internal wall. The portion has a radio-wave propagation space surrounded by first and second metal internal walls parallel to a radio-wave electric field, and third and fourth metal internal walls perpendicular to the field. The exterior shape of the absorber is a parallelepiped. The absorber has a rear-end surface positioned at a predetermined distance from the terminating wall and parallel to the terminating wall or is provided against the terminating wall. The surface of the absorber having the largest rectangular area is on the third or the fourth metal internal wall.

    摘要： A disk-shaped reflecting plate 3 for reflecting an electric wave emitted out of an aperture 1a of a circular waveguide 1 is placed a location which is just opposite to the aperture 1a of the circular waveguide 1, and a ring-shaped waveguide 4 for shaping the radiation characteristic of the electric wave reflected by the disk-shaped reflecting plate 3 to a rotational symmetrical radiation characteristic is disposed around the perimeter of the disk-shaped reflecting plate 3. Thereby, even when many grooves 4a need to be formed in order to make the electric wave have a rotational symmetrical radiation characteristic, it is not necessary to increase the size of the disk-shaped reflecting plate 3 in the direction of its radius.
