Abstract: Disclosed herein are an apparatus and method for transmitting and receiving an RFID signal using beamforming. The apparatus for transmitting and receiving a Radio Frequency Identification (RFID) signal using beamforming according to an embodiment includes a reception unit for receiving power and RFID data signals from an RFID reader, a control unit for adjusting opening/closing periods of switches corresponding to respective paths through which the RF data signals pass, thus controlling the paths, and a transmission unit for converting phases of RF data signals, which are distributed and transmitted to the paths, in response to the opening/closing periods of the switches, and then transmitting beams corresponding to the RF data signals while converting a pattern of the beams.
