Abstract

Il est proposé un dispositif de contrôle de faisceaux radiofréquences (10) comprenant un ensemble de cellules (100). Chaque cellule comprend un cadre de support (130) et un élément d’excitation (150), et réalise une émission et/ou une réception de faisceaux invariante selon la direction de propagation du faisceau. Le cadre est inscrit dans une forme généralement tubulaire, orientée selon l’axe Z d’un repère (X,Y,Z), ayant une section transverse de périmètre P, et comprend une entrée (131), une sortie (132) et un nombre N de fentes (133-n) entre la sortie et une position Zo située entre l’entrée et la sortie. Chaque fente a une largeur variable le long de Z. La largeur de fente a une valeur minimale à la position Zo, et une valeur maximale au niveau de la sortie déterminée en fonction du périmètre P et du nombre N. Figure pour l’abrégé : [Fig.3]
