Abstract :
A new ultra-high frequency radio frequency identification (UHF RFID) reader which baseband module is based on ARM processor and FPGA chip has been designed and implemented to satisfy EPC Class-1 Generation 2 protocol. The reader consists of three parts: baseband signal processing board, radio frequency transceiver and interface board. 90 degree phase-shift microstrip line is used in the radio-frequency board to achieve the IQ conversion, saving the power divider component compared to the conventional homodyne scheme. The baseband controller has faster processing speed than the controller using MCU and is more suitable for the study of anti-collision algorithm and encryption algorithm in RFID.
