RFID READER BASED ON AUTOMATIC MATCHING NETWORK AND CONTROLLING METHOD THEREOF

摘要

This specification is related to a kind of RFID reader and is based on automatic match circuit and control method, can be realized optimum impedance circuit and passes through inverse probability detector and impedance tuner. For this reason,The RFID reader is based on automatic match circuit, includes that modulator-demod generates high frequency (HF) signal according to this specification; Impedance tuner sends the HF signal antennas generated; Antenna transmitting transmitting HF signals; Inverse detection device detection back reflection and impedance tuner; Control unit generates control signal, corresponds to the inverse probability detected and the impedance value for controlling impedance tuner, the control signal based on generation including impedance value. ;The 2014 of copyright KIPO submissions
