Abstract :
The research on surface acoustic wave (SAW) tag has lasted many years. However, the application and promotion are unsatisfactory due to the inherent defects of the manufacturing technology of the large capacity SAW tag. From the perspective of practical production, this paper proposes a novel design of SAW tag to reduce costs. The method is based on the correlation IDT and permutations and combinations theory. At the same time, some ideas about the reader structure for this SAW tag are given.
