Abstract

Disclosed ae 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.
