Abstract

La présente invention concerne un support de données portable (14, 24) comprenant un premier circuit oscillant électrique (2) qui présente une première bobine-antenne (10, 20, 26) et un premier consommateur électrique (6), ainsi qu'au moins un deuxième circuit oscillant électrique (4) qui présente une deuxième bobine-antenne (12, 22, 28) et un deuxième consommateur électrique (8), la première bobine-antenne (10, 20, 26) et la deuxième bobine-antenne (12, 22, 28) étant agencées géométriquement l'une par rapport à l'autre de telle sorte qu'il n'y ait aucune inductance mutuelle entre la première bobine-antenne (10, 20, 26) et la deuxième bobine-antenne (12, 22, 28).
