MIRROR REFLECTED BEAM ANTENNA DEVICE

PURPOSE:To obtain a desired radiation pattern by individually varying the arrangement positions of mirror finished surface sites divided into plural parts in the radiating(transmitting) direction of a radio wave, and partially varying the angle of reflection. CONSTITUTION:Mirror finished surface sites 16a-16e are designated, and a command radio wave W including the information of the moving amounts of the arrangement positions in the radiating(transmitting) direction of the radio wave is transmitted through a command transmitting part 30 and an antenna 32. In a satellite station 10, a control signal Sa obtained by modulating the command radio wave W from a ground station 12 by a command receiving part 22 is supplied to a switch 26, a variable signal Sb is outputted to a driver 24, and a driving signal Sc is supplied to a switch 26. Then, linear actuators 18a-18e are selected by a switch 26 according to the control signal Sa, the driving signal Sc is supplied, the mirror finished surface sites 16a-16e are moved to an arrow (m) direction(shown in a figure) based on the moving amounts in the signal, and the radiation pattern is made suitable to a prescribed service area.
