Mechanism analysis and Application Research on chipless RFID tag coding 

 Abstract RFID as a new automatic identification technology, with small size, large capacity, long life, reusable, etc., the technology and the Internet and communication technology, enables tracking and sharing of information on a global scale items. With the continuous development of the technology, its applications are increasingly expanding, has become a hot research field, has broad application prospects. This paper describes the chipless RFID tag encoding works, technical features and development prospects, as well as the tag antenna HFSS simulation design. In this paper, experimental studies done on the basis of helical filters for simulation made a total of five experiments, choose the most suitable material for the substrate spiral filter. Next, the internal structure of spiral filter on the notch frequency, change the frequency by the final conclusion to increase the degree of recognition of RFID. Through the study of this experiment, it is effective to reduce the cost of RFID tags, better go into real-world applications, especially in terms of promoting the development of things.
