  • METHOD AND APPARATUS FOR LOCATING PASSIVE INTEGRATED TRANSPONDER TAGS
    Publication number: 20210100476
    Abstract: An apparatus for locating an embedded passive integrated transponder (PIT) tag is provided. An embodiment of the locating apparatus includes a resonator capable of electromagnetically coupling to the PIT tag, and a feedback circuit connected to the resonator and configured to monitor a load conductance of the resonator. A distance between the resonator and the PIT tag is indicated by a change in the monitored load conductance when the resonator and the PIT tag are electromagnetically coupled. Another embodiment includes a resonator capable of stimulating a response signal from a PIT tag, and a processing circuit capable of calculating the distance between the resonator and the PIT tag based on the amplitude of the response signal.
