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.

De façon générale, la présente invention décrit une étiquette RFID conçue pour que l'étiquette soit dissimulée sans qu'un signal d'interrogation ne soit bloqué par la main ou une autre partie du corps d'un utilisateur. En particulier, l'étiquette RFID est conçue pour être longue et étroite et pouvoir être placée discrètement sur ou dans un livre, mais dépasse la main d'un utilisateur tenant le livre par le dos sur ou à proximité de son centre. L'étiquette RFID comprend un segment dipolaire et un segment de boucle couplé au segment dipolaire. Le segment de boucle de l'antenne dipolaire modifiée dote l'antenne d'une intensité de signal plus importante que les antennes dipolaires classiques. De plus, le segment de boucle conductrice offre également des capacités d'adaptation d'impédance améliorées qui permettent à l'antenne dipolaire modifiée de s'adapter à l'impédance d'une puce de circuit intégré (CI) de l'étiquette RFID.
