Abstract

L’invention concerne une antenne passive comportant un cadre blindé, par exemple une antenne pour produire un champ magnétique radio-fréquence connu dans un laboratoire. Une antenne passive selon l’invention comporte : un premier élément (1), le premier élément étant une ligne de transmission ayant un conducteur externe (11) et un conducteur interne (12), le premier élément étant une partie d’un cadre blindé ; un deuxième élément (2), le deuxième élément étant une ligne de transmission ayant un conducteur externe (21) et un conducteur interne (22), le deuxième élément étant une partie du cadre blindé, une extrémité du conducteur interne de la ligne de transmission du deuxième élément étant directement couplée à une extrémité du conducteur interne de la ligne de transmission du premier élément ; une base (3) ; un dispositif linéaire à accès unique comportant une résistance et un condensateur ; et un accès de l’antenne passive. Figure pour l’abrégé : Figure 6.
