    • An RFID reader is provided selectivity to improve between a transceiver and a received by remarkable isolation between a transmitting end and a receiving end, and increase recognition of a receiving signal by using circular polarization signals not interfering with each other. An antenna transceives an RFID signal, and a combiner(130). The combiner is connected to the receiver(160) and the transmitter(150) by including a plurality of ports, and has a directional signal transfer property for separating the signal inputted through the predetermined port among the ports. The antenna includes the first antenna(110) transceiving the RFID signal in an LHCP(Left Hand Circular Polarization) mode and the second antenna(120) transceiving the RFID signal in a RHCP(Right Hand Circular Polarization) mode. The combiner has four ports and a section formed by four ports has a phase difference of quarter lambda. An isolator(140) restricting signal input is installed to the port connected to the transmitter.
