An article identification system includes a transceiver (20) that generates a request signal and transmits the request signal, where the request signal requests information corresponding to an article (35). A transponder (40) is coupled to the article, receives the request signal, and generates an output signal in response to the request signal, where the output signal includes information corresponding to the article. A loop antenna (50) proximate to the transponder enhances the output signal. The transceiver detects the enhanced output signal and receives the information corresponding to the article.
L'invention concerne un système d'identification d'article comprenant un émetteur-récepteur (20) produisant un signal de demande et émettant celui-ci, le signal de demande demandant des informations correspondant à un article (35). Un transpondeur (40) est couplé à l'article, reçoit le signal de demande et produit un signal de sortie en réponse au signal de demande, le signal de sortie comprenant des informations correspondant à l'article. Une antenne cadre (50) située à proximité du transpondeur améliore le signal de sortie. L'émetteur-récepteur détecte le signal de sortie amélioré et reçoit les informations correspondant à l'article.
