Abstract: The invention relates to a method for locating an RFID tag (1) using at least one RFID reading device (2). The invention is characterized in that the RFID reading device (2) transmits a query signal (3) which comprises a broadband signal (4); the RFID tag (1) modulates the query signal (3) with a code signal (5) by varying the antenna impedance of the RFID tag and reflects said signal as a reflected signal (6); the RFID reading device (2) receives the reflected signal (6) and obtains the code signal (5) and a scattered broadband signal (7) from the reflected signal; the RFID reading device (2) determines a travel time of the broadband signal (4) by comparing the broadband signal (4) with the scattered broadband signal (7); the RFID reading device (2) determines the distance between the RFID reading device (2) and the RFID tag (1) from the travel time difference.

Abstract: An automatic data collection system tracks articles by providing a robust electromagnetic (EM) field within an enclosure in which the articles are stored. Respective data carriers, such as RFID tags, attached to each article respond to the electromagnetic field by transmitting unique data identified with each article. Where the frequency of the EM field coupled to the enclosure differs from the natural resonance frequency of the enclosure, the placement of a probe to couple energy to the enclosure is selected to have the reflected phase of the EM energy from walls equal at the probe location thereby producing a robust EM field to activate and/or detect data carriers.
