  • the sticker type is one of most widely used methods, however the sticker type is restricted in adhesive strength and durability in harsh environments. Also, since a tag formed by molding protects an RFID chip, the tag may be used in harsh environments.

Abstract

L'invention concerne un œillet RFID et un procédé de fabrication de l'œillet RFID. L'œillet RFID comprend : une base d'œillet faite d'un matériau conducteur et comprenant un anneau qui est mis en contact sur un objet, la base d'œillet comprenant un corps formé intégralement avec l'anneau, le corps traversant l'objet et étant fixé sur l'objet, une fente est formée dans la base d'œillet, une partie de résistance élevée est formée sur la base de la fente et formée longitudinalement dans la base d'œillet ; et un module de circuit RFID connecté électriquement à chacune des parties séparées qui sont séparées par la fente et formant un circuit qui utilise la base d'œillet comme une antenne. Dans une étiquette RFID, un matériau conducteur peut interférer avec une transmission et une réception de données régularisées, cependant dans la présente invention, une transmission et une réception de données régularisées peuvent être réalisées par l’utilisation du matériau conducteur comme une antenne, par conséquent la productivité peut être améliorée, les coûts de fabrication pour l'étiquette RFID peuvent être réduits et un accrochage solide peut être fourni par l'utilisation d'une structure d'œillet conventionnelle.
