  • System and method for wireless communications
    Patent number: 9848252
    Abstract: A method and system for estimating position of a moving RFID tag is provided. The method includes transmitting at least one interrogator signal; receiving, at an interrogator antenna, a reflected signal from the RFID tag; determining phase changes of the reflected signal with respect to the phase of the at least one interrogator signal; weighting the phase changes based on instant power corresponding to the phase changes; producing a phase trajectory for the reflected signal based on the weighted phase changes; and estimating position of the RFID tag relative to the interrogator antenna based on the peak of the phase trajectory for the reflected signal.
    Type: Grant
    Filed: March 28, 2012
    Date of Patent: December 19, 2017
    Assignee: Lyngsoe Systems
    Inventors: Patrick Claus Friedrich Eggers, Boyan Radkov Yanakiev, Gert Frølund Pedersen, Alex Oprea

  • System and method for wireless communications
    Patent number: 8149093
    Abstract: A method of detecting position of a moving RFID tag relative to an antenna, includes continually receiving a signal from the RFID tag at the antenna. The phase of the received signal over a time period is detected and, based on a maximum detected phase, the position of the RFID tag relative to the antenna is detected.
