Abstract

L'invention est une antenne à plaques multifaisceau formée sous la forme d'un réseau d'alimentation (15) sur un substrat microruban de dessous avec des plaques (13) superposées montées sur un substrat de dessus. Ces plaques sont disposées en groupes linéaires montés en série (13a, 13b, 13c), chacun d'eux étant un groupe résonant et pouvant comporter des circuits ouverts à chaque extrémité. Une architecture de lignes d'alimentation à ondes progressives (15a, 15b, 15c) est utilisée et, dans une concrétisation particulière de l'invention, le nombre total de faisceaux qui peuvent être produits est le double du nombre de lignes d'alimentation. L'invention est utile aux petites stations terriennes de communication par satellite et peut fonctionner aux environs de 10 GHz.
