Abstract

Dispositif de transmission radio-électrique hyperfréquence à faisceaux multiples comprenant une antenne 11 et une électronique de commutation. L'antenne comporte plusieurs cornets 12, 13, 14 et 15, de rayonnement hyperfréquence et un jeu de filtres passe-bande associé à chaque source et formant multiplexeur. Des organes de couplage 22, 23, 24 et de commutation 28, 29, 33 permettent de diriger la puissance d'émission sur les divers canaux vers les cornets correspondants à des sous-régions à couvrir à partir de l'antenne. Application aux satellites relais de télévision.
