Abstract

Antenne multifaisceaux à pointage réglable La présente invention concerne une antenne multifaisceaux (10) à pointage réglable comprenant un dispositif de réflexion (12) unique et une pluralité de sources rayonnantes disposées en regard du dispositif de réflexion (12) et aptes à émettre et/ou à recevoir des signaux radioélectriques, le dispositif de réflexion (12) définissant un centre, un plan focal et un foyer se trouvant dans ce plan focal. L’antenne (10) est caractérisée en ce qu’au moins l’une des sources rayonnantes, dite source mobile, est mobile sensiblement indépendamment de la ou de chaque autre source rayonnante dans une surface de balayage pour régler le pointage de l’antenne (10), la surface de balayage coïncidant avec le plan focal ou étant tangente à celui-ci au foyer.
