In a broadcasting satellite, signals transmitted through an up transmission line of a Ka band, which includes a plurality of communication channels, are received by a Ka-band antenna. The signals received by the antenna are passed through band-pass filters 12 to thereby extract a broadcasting signal transmitted through each communication channel. Those of the thus- extracted broadcasting signals, which have been transmitted through predetermined communication channels, are synthesized by each of synthesizers 15, then amplified by a corresponding one of high power amplifiers 16, and output to a corresponding one of a plurality of primary radiators 53 employed in an S-band antenna. The S-band antenna transmits each synthesized signal to a predetermined area that corresponds to a corresponding primary radiator 53. Thus, the system can be made to a simple structure, and the service area can be changed for each broadcasting signal.

L'invention concerne un système de radiodiffusion par satellite et un satellite de radiodiffusion de conception simplifiée et capable d'opérer des modifications dans la zone de service conformément à des signaux de radiodiffusion. Dans le satellite de radiodiffusion, une antenne en bande Ka reçoit des signaux arrivant par une ligne en amont composée de plusieurs canaux de communication en bande Ka et des filtres passe-bande (12) extraient des signaux de radiodiffusion en filtrant les signaux reçus de l'antenne. Après la synthèse par des synthétiseurs (15) des signaux de radiodiffusion extraits, reçus par des canaux de communication prédéterminés et l'amplification par des amplificateurs à grande puissance (16) de la puissance des signaux synthétisés, les signaux amplifiés sont envoyés à des radiateurs primaires prédéterminés sélectionnés parmi plusieurs radiateurs primaires (53) d'une antenne de bande S et sont transmis à des zones définies correspondant aux radiateurs (53) de l'antenne de bande S.
