摘要：
An apparatus and method for removing a transmission leakage signal from a radio frequency identification (RFID) reader are provided. The apparatus includes a removing unit having a device of a large impedance and a phase shifter capable of a wide range phase change with respect to a leakage signal, thereby optimally removing the transmission leakage signal irrespective of a change in the frequency characteristics and a change in the length of a cable.
