Abstract[English]
Disclosed are fabric-based radio frequency identification (RFID) tags and methods of manufacture. The method is characterized by forming a knitted fabric from at least one primary non-conductive fiber and a secondary conductive fiber, wherein the secondary conductive fiber is distributed within the knitted fabric to form a plurality of dipole antennas; integrating an RFID inlay with each of the plurality of dipole antennas to form pairs of inlays and antennas; and, cutting the knitted fabric to separate each of the pairs of inlays and antennas into individual RFID tags. The RFID inlay comprises an RFID integrated circuit (IC) and a loop antenna on a substrate; the RFID inlay is positioned on the fabric-based antenna such that the loop antenna is inductively coupled to a dipole antenna.[French]
L'invention concerne des étiquettes d'identification par radiofréquence (RFID) à base de tissu et des procédés de fabrication. Le procédé est caractérisé par la formation d'un tissu tricoté à partir d'au moins une fibre non conductrice primaire et d'une fibre conductrice secondaire, la fibre conductrice secondaire étant distribuée à l'intérieur du tissu tricoté pour former une pluralité d'antennes dipôles ; l'intégration d'une incrustation RFID avec chacune de la pluralité d'antennes dipôles pour former des paires d'incrustations et d'antennes ; et la découpe du tissu tricoté pour séparer chacune des paires d'incrustations et d'antennes en étiquettes RFID individuelles. L'incrustation RFID comprend un circuit intégré RFID (IC) et une antenne cadre sur un substrat ; l'incrustation RFID est disposée sur l'antenne à base de tissu de telle sorte que l'antenne cadre est couplée par induction à une antenne dipôle.
