Abstract

Système antennaire amélioré et dispositif de découplage associé Ce système antennaire comporte au moins une antenne élémentaire, un plan métallique prévu autour de l’antenne élémentaire, et un dispositif de découplage (150) disposé sur le plan métallique, le dispositif de découplage étant du type structure d’absorption électromagnétique tridimensionnelle constituée d’une pluralité de cellules disposées en réseau, chaque cellule (152) comporte, empilées selon une direction normale au plan métallique, une embase (154) surmontée d’une paroi relevée, le système antennaire étant caractérisé en ce que la paroi relevée (156) est conformée de manière à former un motif évidé de piégeage des ondes électromagnétique.
