Abstract

L’invention concerne un circuit d’antenne RFID, comportant un support (2) isolant et un conducteur (3) s’étendant de la patte (21) à la patte (22). Suivant l’invention, le conducteur (3) comporte un tronçon inférieur (31) connecté à un tronçon supérieur (32), le tronçon (31) comporte sous la patte (21) une partie (33) inférieure conductrice nue d’extrémité, le tronçon (32) comporte sur la patte (22) une partie (34) supérieure conductrice nue d’extrémité, les embases (4, 5) comportant des organes (6, 7) de fixation aptes à coopérer pour fixer l’embase (4) à l’embase (5) dans une position de fixation, de manière à appuyer la partie (33) sur la partie (34) suivant la direction transversale (Z), pour que le support (2) forme une boucle (100) autour de la direction longitudinale (X) et pour que le conducteur (3) forme une spire (30) d’inductance disposée autour de la direction (X). Figure pour l’abrégé : Figure 15The invention relates to an RFID antenna circuit, comprising an insulating support (2) and a conductor (3) extending from the leg (21) to the leg (22). According to the invention, the conductor (3) comprises a lower section (31) connected to an upper section (32), the section (31) comprises under the tab (21) a lower end conductive part (33), the section (32) comprises on the tab (22) an upper part (34) conductive bare end, the bases (4, 5) comprising fixing members (6, 7) able to cooperate to fix the base ( 4) to the base (5) in a fixing position, so as to press the part (33) on the part (34) in the transverse direction (Z), so that the support (2) forms a loop (100 ) around the longitudinal direction (X) and so that the conductor (3) forms a coil (30) of inductance arranged around the direction (X).
