Abstract

L'invention a pour objet de donner à un transpondeur à micro-ondes à portée élevée, un encombrement en hauteur limité correspondant à la norme des cartes à puce. A cet effet, l'invention fait intervenir une batterie mince. La batterie mince (40) sert à la fois d'antenne et d'antenne plaque de dimensions correspondantes. De façon alternative, la batterie mince (40) peut servir de support à une antenne plaque (28). La surface cathodique (30) de la batterie mince (40) sert de surface de masse de dimensions importantes. Elle porte une entrée (26) sur laquelle est formée une doublure en cuivre qui sert d'antenne plaque (28), ladite doublure ayant une longueur ou une largeur (λ/2) déterminée en fonction de la fréquence de fonctionnement.
