Abstract

In traditional Radio Frequency Identification (RFID) reader system, the electromagnetic energy cannot be transferred as much as possible, which is caused by the discrete resonance frequency of antenna. The energy transferred distance should be reduced by this reason. In this paper, Direct Digital Synthesizer (DDS) technique and the adaptive frequency work mode are applied in RFID reader. Under this condition, the resonance frequency of RFID tag can be searched automatically by the reader. Therefore, the resonance frequency error can be decreased, and the match between reader and tag can also be optimized. As the result, the reading distance of RFID system is expanded. In this paper, the RFID system is controlled by STC8952, and DDS is realized by AD9854.
