Method of making RFID devices on fabrics by stitching metal wires

摘要

An RFID device assembly is fabricated by stitching an electrically conductive wire into a fabric as a pattern that forms an antenna. The two ends of the electrically conductive wire are positioned for coupling to antenna contact pads on an RFID device. The RFID device is attached to the fabric either before or after the electrically conductive wire is stitched to the fabric.
