Abstract

L’invention concerne une antenne active comportant un cadre blindé, par exemple une antenne pour les communications radio et/ou les mesures de champs électromagnétiques. Une antenne active 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 un conducteur électrique, le deuxième élément étant une partie du cadre blindé ; une base (3) ; un dispositif linéaire à accès unique (4) ayant, à une fréquence, une résistance et une réactance, la résistance étant supérieure à une valeur absolue de la réactance ; un filtre passif linéaire ; un amplificateur ayant une entrée et une sortie, l’entrée de l’amplificateur étant couplée à une sortie du filtre passif linéaire ; et un accès de sortie, l’accès de sortie étant couplé à la sortie de l’amplificateur. Figure pour l’abrégé : Figure 3.
