Abstract

L'invention concerne un circuit d'antenne RFID/NFC, comportant une antenne (L) formée par au moins trois spires (S) sur un substrat, l'antenne ayant une première borne (D) d'extrémité et une deuxième borne (E) d'extrémité, deux bornes (1, 2) d'accès pour la connexion d'une charge, une capacité (C1) d'accord à une fréquence d'accord prescrite, une prise intermédiaire (A) reliée à l'antenne (L) et distincte des bornes (D, E), un moyen (CON1A) de connexion de la prise intermédiaire (A) à la borne (1), un moyen (CON2E) de connexion de la borne (E) d'extrémité à la borne (C1E) de capacité. Suivant l'invention, des troisièmes moyens (CON31, CON32) de connexion de la borne (C1X) de capacité et de la deuxième borne (2) d'accès à respectivement un premier point (P1) de l'antenne (L) et à un deuxième point (P2) de l'antenne (L) relié au premier point de l'antenne (L) par au moins une spire (S) de l'antenne (L), sont prévus.
