Abstract

PURPOSE:To compensate the blocking by the primary radiator, by providing a subradiator having a size of aperture almost equal to the primary radiator at the back of the primary radiator. CONSTITUTION:A subradiator which has Z axis of main radiation direction is installed at the back of a primary radiator 2. An output signal from a transmission source 9 enters distribution circuit 5 and is radiated from each element antenna 4 to space and reflected at a reflection mirror 1 to form the 1st beam. On the other hand, a part of an output signal from the transmission source 9 enters a distributor 8 through a phase adjuster 11 and an amplitude adjuster 12 via a directional coupler 10 to form the 2nd subbeam through the radiation from each element antenna 7 to space. The side lobe increased with blocking of the primary radiator can be compensated by suitably overlapping the 1st and 2nd beam.
