Abstract

La présente invention concerne un système d'antenne qui comprend : un premier élément d'antenne couplé réciproquement à un second élément d'antenne, le couplage réciproque entre les premier et second éléments d'antenne induisant un premier courant dans le second élément d'antenne; et un élément de couplage qui est disposé au moins partiellement entre les premier et second éléments d'antenne. Selon l'invention, l'élément de couplage est couplé réciproquement à chacun des premier et second éléments d'antenne, et l'élément de couplage est configuré de façon à induire un second courant dans le second élément d'antenne qui annule au moins partiellement le premier courant.
