Abstract

L’invention concerne un dispositif (1) de communication en haute fréquence et de rechargement par induction d’un appareil comprenant une surface de rechargement (5), au moins une antenne de rechargement (6) émettant un champ magnétique à une basse fréquence et une couche (7) en matériau ferromagnétique. Le dispositif comprend au moins une antenne de communication (31, 32) et une plaque de circuit imprimé (2). L’antenne de communication (31, 32) est sous la forme d’une bobine entourant localement la couche (7) en présentant un axe de symétrie se trouvant dans un plan parallèle à la couche (7). Le matériau de la couche (7) est sélectionné pour présenter à haute fréquence une partie imaginaire de perméabilité suffisamment élevée pour engendrer des fuites sur une surface de la couche (7) s’étendant perpendiculairement à la couche tout en conservant à basse fréquence une partie imaginaire de perméabilité suffisamment basse pour permettre le rechargement par induction.
