Abstract

Abstract: Radio frequency identification (RFID) technique is a kind of wireless, automatic identification technology that is being widely used. Compared to other identification methods such as bar code and two‐dimensional code (quick response code or QR code), the RFID technique has several remarkable merits, such as long reading distance, strong penetrating ability, pollution resistance, high reading efficiency, small size, and large information storage. However, the technique involves high cost and cannot be accepted by cost‐sensitive commodities or applications. To reduce its cost, chipless RFID tags were proposed in recent years using surface acoustic wave (SAW) to read and store the information is one such RFID tags. The tags feature small size, high flexibility, strong radiation resistance, high consistency and repeatability, as well as high temperature stability. In this paper, we propose a novel design for the SAW‐based RFID tags by using the commercial software COMSOL and analyze the performance of SAW tags with different structures.
