摘要： A radio frequency identification (RFID) reader includes an antenna unit and a signal processing unit. The antenna unit splits an input RF signal into a plurality of signals and respectively transmit the split signals through a plurality of antennae by setting the amplitudes or phases of the split signals to be different from one another. The signal processing unit is connected to the antenna unit through one transmission line, and transmits an RF signal to which a DC signal is added to the antenna unit. Accordingly, the amplitude and phase of the RF signal are set variable, so that it is possible to extend the identification range by dynamically controlling an antenna radiation pattern of the RFID reader and to stably communicate with the tag by decreasing the error rate of reception data.
