Abstract

PURPOSE:To ensure a flexible service with just an antenna, by radiating simultaneously both the forming beam and the multibeam through a multihorn antenna. CONSTITUTION:The forming beam signals are supplied from transponders 71-7s to a feeding electric power distribution network 5 via a wave synthesizer 6, and the signals distributed through the network 5 so as to possess a proper amplitude phase energize horns 2a, 2b-. As a result, a forming beam 8 is radiated. On the other hand, transponders 121, 122- supply the signals different from the forming beam and having frequencies fA, fB- to wave synthesizers 11a and 11b- provided between the network 5 and transmission/reception branching filters 4a, 4b- of each horn directly with no intervention of the network 5 or via only a wave synthesizer 9. Thus the signals supplied independently to the horns 2a, 2b- radiate the independent beams, and as a result spot beams 10a-10x are radiated.
