  • Dynamic compensation of a phased array RFID reader
    Patent number: 11210480
    Abstract: Methods and devices for performing dynamic compensation of a phased array RFID reader are disclosed herein. An example method includes configuring an RFID reader having an antenna array to compensate for determined antenna element phase-shift errors. The method includes exciting a reference antenna element of the antenna array, emitting an emitted signal, receiving the emitted signal via a receiver antenna element of the antenna array, and generating a received signal. The method further includes determining, by a processor, a phase shift of the received signal relative to the emitted signal, and determining a phase-shift error. The method then includes configuring the RFID reader to compensate for the determined phase-shift error associated with the receiver antenna element in response to receiving an RFID tag signal.
