A radio frequency identification (RFID) reader includes a transmitter generating a transmission signal for transmission to a tag, a receiver receiving a response signal from the tag, a leakage compensator compensating a leakage signal leaked from the transmitter to the receiver in response to a leakage control signal, and a control unit performing a leakage test operation by applying a test signal to the transmitter, and calculating and storing a leakage parameter for generating the leakage control signal using a level difference of the test signal and a level difference of a test leakage signal leaked to the receiver.
