Therefore, in the case of generally used existing tags in a frequency bandwidth of less than 13.56 MHz, there are basic limitations in which an antenna has to be formed in the type of a coil by using an inductive coupling method, the size of the antenna has to be more than several cm, and external housing may not be composed of metal material.

Abstract

L'invention concerne un oeillet conçu pour une étiquette d'identification par radiofréquence (RFDI), qui remplit une fonction d'identification sans contact. Cet oeillet comprend une base d'oeillet, une antenne intégrée, et un module de circuit RFID. La base d'oeillet est composée d'un matériau plastique, et comprend un bord qui est intimement fixé sur un objet, ainsi qu'une partie cylindrique qui traverse l'objet à fixer. Une extrémité de la partie cylindrique est enroulée pour être intimement fixée sur l'objet, tandis que l'antenne intégrée et le module de circuit RFID sont fixés sur l'objet. Le module de circuit RFID qui est fixé sur l'objet utilise l'antenne intégrée pour émettre et recevoir des données avec un lecteur externe. Dans la mesure où la base de l'oeillet est composée d'un matériau plastique, le module de circuit RFID peut communiquer sans entrave avec le lecteur. Une structure d'oeillet traditionnelle est utilisée, ce qui permet d'augmenter la quantité de production, de réduire le coût d'une étiquette RFID, et d'établir un contact durable.
