The frequency bands and the technical standards of the RFID tags are often different, and the RFID reader often has very narrow operating frequency bands and can’t support mutl-protocal, which will cause problems when the RFID reader read the data from the RFID tags. To overcome this problem, a smart multi-frequency bands and multi-protocol RFID reader is research and designed. The system scheme of the adjustable operating frequency and the multi-protocol of the RFID reader is proposed. In the hardware system, the ST’s STM32F103VET6 chips and the TI’s CC1101 chips are selected to configu-rated as the mcu and RF transceiver modules. The adjustable frequency matching network is also de-signed, and the multi-protocol functions are realized in the software system. In addition, the bending wire dipole antenna is studied and simulated to reduce the size of the antenna. The reader has a strong adapta-bility, low cost, which can bring the convenience of RFID applications.
