  • Patent number: 8717244
    Abstract: In general, the disclosure describes an RFID tag designed such that the tag is both covert and not easily blocked from the interrogation signal by the hand or other body part of a person. In particular, the RFID tag is designed to have a long, narrow aspect that allows placement of the tag in locations on or in a book that are inconspicuous to the casual observer while extending beyond a hand of a person holding the book by the spine on or near a geometry centerline. The RFID tag includes a dipole segment and a loop segment coupled to the dipole segment. The loop segment of the modified dipole antenna provides the antenna with larger signal strength than conventional dipole antennas. Moreover, the conductive loop segment also provides improved impedance matching capabilities to allow the modified dipole antenna to match the impedance of an integrated circuit (IC) chip of the RFID tag.

  • Publication number: 20090320998
    Abstract: In general the disclosure relates to manufacturing methods for producing conductive patterns on flexible substrates. For example, a layer of a metal powder composition is deposited onto an adhesive overlaying a substrate. Pressure is applied to the metal powder composition on the adhesive coated substrate web by a die having one or more projections, in order to reproduce a pattern on the substrate. The metal powder is compressed by the projections of the die, thereby densifying the powder and causing it to adhere to the adhesive in a reproduction of the die pattern. The metal powder does not adhere substantially in uncompressed regions, and may be removed. In this manner, a metal powder composition may be densified and adhered to a substrate forming a web of flexible circuit elements, for example, circuit elements such as antennas, resistors, capacitors, inductive coils, conduction pads and the like.
