Abstract
Un élément récepteur-réémetteur pour système de surveillance est formé par un cadre d'antenne constitué d'une feuille de clinquant divisée en trois parties. La première partie est une partie en U présentant une largeur et se raccorde à une partie médiane de largeur réduite. Une diode semi-conductrice est connectée dans la partie médiane. L'extrémité opposée de la partie médiane est connectée à une partie rectangulaire élargie. Les parties sont telles que la diode voit à la fréquence porteuse une inductance d'un coté et une capacité de l'autre.
