Abstract

Système d'antennes comprenant une première antenne (107) placée sur le logement d'un premier dispositif (103) et un élément passif (108) placé sur le logement d'un deuxième dispositif (102). Les logements se déplacent l'un par rapport à l'autre pour rétracter le dispositif en mode d'attente et le déployer en mode de communication active. La première antenne (107) et l'élément passif (108) sont positionnés sur leurs logements respectifs, de manière à établir un couplage passif lorsque les logements sont rétractés; ils ne sont pas couplés lorsque les logements sont déployés.
