Abstract
Printed integrated circuitry and attached antenna and/or inductor for sensors, electronic article surveillance (EAS), radio frequency (RF) and/or RF identification (RFID) tags and devices, and methods for its manufacture. The tag generally includes printed integrated circuitry on one carrier and an antenna and/or inductor on another carrier, the integrated circuitry being electrically coupled to the antenna and/or inductor. The method of manufacture generally includes of printing an integrated circuit having a plurality of first pads on a carrier, forming an antenna and/or inductor having a plurality of second pads on a substrate, and attaching at least two of the first pads of the printed integrated circuit to corresponding second pads of the antenna and/or inductor. The present invention advantageously provides a low cost RFID tag capable of operating at MHz frequencies that can be manufactured in a shorter time period than conventional RFID tags that manufacture all active electrical devices on a conventional wafer.
