Abstract

L'invention concerne un circuit d'antenne RFID et/ou NFC, comportant au moins une capacité (CO) d'accord ayant une borne (11) de capacité et une deuxième borne (12), et des spires tridimensionnelles, la capacité (CO) et les spires étant reliées en série entre une première borne (BAI) et une deuxième borne (BA2), aptes à reliées à une charge (CHA). L'invention est caractérisée en ce que les spires sont formées par au moins un premier groupe (L1) de premières spires tridimensionnelles reliées entre la borne (BAI) de connexion et un premier point (1) d'une des première spires, et par au moins un deuxième groupe (L2) de deuxièmes spires tridimensionnelles, reliées entre la borne (BA2) de connexion et un deuxième point (2) d'une des deuxièmes spires, le point (1) étant relié à la borne (11) de capacité et le point (2) étant relié à la deuxième borne (12) de capacité, le point (1) étant éloigné du point (2) par une distance (D), qui est supérieure à un intervalle (Di1) entre les premières spires et qui est supérieure à un intervalle (Di2) entre les deuxièmes spires.
