Abstract

Un système d'antennes plates à plateaux est formé d'au moins deux plateaux (4, 5, 6), une mince tôle conductrice (45, 56) étant interposée entre chaque paire de plateaux. Ces plateaux sont configurés de manière à définir des pavillons et au moins un canal à côtés ouverts qui est fermé par la tôle conductrice afin de former un guide d'ondes destiné à fournir des signaux à destination ou en provenance de l'antenne. Les plateaux peuvent être chacun réalisés dans une matière plastique moulée présentant une couche conductrice sur au moins une partie de la surface et formée par métallisation du moulage en plastique.
