Abstract

La présente invention concerne un dispositif (10) pour une unité d'émission et de réception (110) d'un système de communication. Le dispositif (10) comporte un premier passage (120A) pour des ondes électromagnétiques et un second passage (120B) pour des ondes électromagnétiques, une surface partiellement transparente (130) qui est transparente pour des ondes électromagnétiques d'une première gamme de longueurs d'onde (180A, 180B) et réfléchissante pour des ondes électromagnétiques d'une seconde gamme de longueurs d'onde (190) différente de la première gamme (180A, 180B), et une première surface rétroréfléchissante (140A) qui rétroréfléchit les ondes électromagnétiques de la première gamme (180A, 180B). Une direction de réflexion des ondes de la première gamme (180A, 180B) est différente d'une direction de réflexion des ondes de la seconde gamme (190) lorsque les ondes électromagnétiques de la première gamme (180A, 180B) ainsi que les ondes électromagnétiques de la seconde gamme (190) entrent par le même passage.
