Patent ID: 7319393

Claim:
A radio-frequency identification (RFID) tag for use with a reader that generates activation energy, the RFID tag comprising: a pair of antennas for receiving activation energy; an RFID circuit for modulating tag energy when activation energy is received by at least one of the antennas and for modulating tag energy when tag energy is received by at least one of the antennas, wherein the antennas and the RFID circuit are each disposed on a respective substrate; a transmission line for operatively coupling the RFID circuit to the antennas, wherein the transmission line includes a plurality of adhesively mountable segments each electrically coupled to a respective one of the antennas and the RFID circuit, the antennas and the RFID circuit being separate adhesively mountable segments; a first one of the antennas for receiving activation energy; a second one of the antennas for radiating activation energy received by the first antenna and for receiving tag energy radiated by an antenna of another RFID tag; and the first antenna for radiating the tag energy received by the second antenna from the other RFID tag; whereby when a plurality of the RFID tags are positioned in sequence in operative proximity with each other, activation energy is propagated through the sequence from one RFID tag to another in one direction, and tag energy is propagate through the sequence from one RFID tag to another in another direction.
