Abstract
Un ensemble coupleur de cornets appariés (10) est utilisé dans un joint rotatif RF pour acheminer un signal électromagnétique. L'ensemble coupleur (10) comporte des premier (12) et second (14) cornets d'alimentation définissant des premier (16) et second (18) axes longitudinaux de cornet respectifs se coupant l'un l'autre au niveau d'un point d'intersection (20). Les premier et second cornets d'alimentation (12, 14) se raccordent à un miroir (22) pour acheminer le signal entre eux avec le point d'intersection (20) se trouvant sur une surface réfléchissante (26) du miroir (22) qui définit une direction normale (30) de celui-ci au niveau du point d'intersection (20). La direction normale (30) est espacée angulairement de façon égale à la fois des premier et second axes longitudinaux de cornet (16, 18). Des première (32) et seconde (34) lentilles se raccordent aux premier et second cornets d'alimentation (12, 14) respectifs et focalisent le signal entre eux et au niveau du point d'intersection (20). Au moins l'un des premier et second cornets d'alimentation (12, 14) est raccordé en rotation par rapport au miroir (22) autour de l'axe longitudinal de cornet (16, 18) respectif.
