Patent

CA 2700641

The invention provides one or more signal line structures that produce an electromagnetic field having a magnitude of at least an interrogation threshold of a radio frequency identification (RFID) tag for a substantial portion of an interrogation region. The signal lines may be made from copper and laid across a shelf in a storage area. The electromagnetic field may cause the tag to backscatter radio frequency (RF) signals to an RFID reader via the signal line. Image

L'invention concerne une ou plusieurs structures de circuit d'acheminement des signaux qui produisent un champ électromagnétique ayant une ampleur d'au moins un seuil d'interrogation d'une étiquette d'identification radiofréquence (RFID) pour une partie importante d'une zone d'interrogation. Les circuits d'acheminement des signaux peuvent être constitués de cuivre et posés sur une étagère dans une zone de stockage. Le champ électromagnétique peut amener l'étiquette à rétrodiffuser des signaux radiofréquences (RF) vers un lecteur RFID via le circuit d'acheminement des signaux.
