Abstract: 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.

Abstract: In order to lessen the deterioration of the VSWR, a plural-reflector antenna system is provided wherein an appropriately shaped vertex matching plate is disposed on the subreflector and electric waves that reenter the primary radiator are cancelled out. The electric waves radiated from the primary radiator are reflected by the subreflector and are radiated into space after being reflected by the main reflector. The passing area in the horn aperture, through which the reflected waves from the vertex matching plate pass, is made to be analogous to the aperture of the primary radiator, by defining the vertex matching plate as an ellipsoid, and by orienting its minor-axis direction in the major-axis direction of the main reflector and its major-axis direction, in the minor-axis direction of the main reflector.
