Abstract

L'invention concerne un ensemble antenne comprenant un premier élément antenne active et un second élément antenne active, pouvant chacun être un dipôle. Un premier groupe de réflecteurs radiofréquence commutables indépendamment est positionné autour d'au moins le premier élément antenne active. Ces premiers réflecteurs radiofréquence commutables peuvent également être positionnés autour du second élément antenne active. En variante, un second groupe de réflecteurs radiofréquence commutables indépendamment peut être positionné autour d'au moins le second élément antenne active. Les réflecteurs commutables permettent une perturbation contrôlée du canal de communication entre l'ensemble antenne et un nud de communications à distance, permettant des communications chiffrées de manière sécurisée.
