A radio frequency identification (RFID) reader for cancelling a leakage signal, comprising:
- a digital unit calculating and storing an amplitude and a phase of the leakage signal;
- and
- a leakage cancellation circuit generating a leakage cancellation signal to cancel the leakage signal in response to a control of the digital unit.
A method for canceling a leakage signal in a radio frequency identification (RFID) reader comprising:
- calculating and storing an amplitude and a phase of the leakage signal from the RFID reader;
- and
- generating a leakage cancellation signal to cancel the leakage signal based on the calculated amplitude and phase of the leakage signal.
