Abstract

PURPOSE:To ensure an easy control for the posture of the satellite assembly by securing a constitution to shift the plane panel secondary reflector and then giving the displacement to the plural units of beams in the same direction and with the same angle via a simple mechanical mobile device. CONSTITUTION:A unit of main reflector 1 and a unit of primary radiator 4 are provided, and secondary reflector 2 is added to guide the electric wave radiated from radiator 4 toward reflector 1. In such reflector antanna, reflector 2 is made into a plane panel secondary reflector which is capable featuring the rotary control around independent shaft 5 and 5' orthogonal to each other via rotary driving device 3. And the phase center, in case primary radiator 4 and 4' are provided, is set within the surface which passes through the position of the mirror image at focus 8 of reflector 1 against perfect conductor plane secondary reflector 13 and 13', and thus the plural units of beams can be displaced in the same direction and with the same angle.
