Abstract
La présente invention concerne un système d'au moins deux unités (1, 2) émettrices et/ou réceptrices d'un signal respectivement à une première ou à une deuxième fréquence, chacune des unités (1, 2) étant reliées individuellement à l'antenne (4) commune par respectivement une première branche (10) et une deuxième branche (20). La première branche (10) ou l'antenne (4) comprend des premiers moyens électroniques passifs (51a) interdisant un passage du signal à la deuxième fréquence vers la première unité (1) et permettant un passage du signal à la première fréquence vers l'antenne (4). La deuxième branche (20) ou l'antenne (4) comprend des deuxièmes moyens électroniques passifs (62a) interdisant un passage du signal à la première fréquence vers la deuxième unité (2) et permettant un passage du signal à la deuxième fréquence vers l'antenne (4).
