Research and Design on Radio Frequency Identification Reader

The function and the fundamental rule of the radio frequency identification (RFID) were introduced in the paper. The protocol of radio frequency identification system and the demand of radio frequency identification system to the radio frequency criterion were analyzed. On the based of analyses, a design scheme and corresponding circuit structure for RFID reader was proposed. The scheme was based on international standard ISO 15693 and worked at the frequency band of 13.56 MHz to identify electron label.
