We discuss the feasibility of surface acoustic wave (SAW) radio-frequency identification (RFID) tags that rely on ultra-wideband (UWB) technology. We propose a design of a UWB SAW tag, carry out numerical experiments on the device performance, and study signal processing in the system. We also present experimental results for the proposed device and estimate the potentially achievable reading distance. UWB SAW tags will have an extremely small chip size (<0.5 x 1 mm(2)) and a low cost. They also can provide a large number of different codes. The estimated read range for UWB SAW tags is about 2 m with a reader radiating as low as <0.1 mW power levels with an extremely low duty factor.
我们讨论了基于超宽带（UWB）技术的表面声波（SAW）射频识别（RFID）标签的可行性。我们提出了一种UWB SAW标签的设计，对该设备的性能进行了数值实验，并研究了系统中的信号处理。我们还给出了所提出设备的实验结果，并估计了潜在可实现的读取距离。UWB SAW标签将具有极小的芯片尺寸（<0.5×1平方毫米）和低成本。它们还可以提供大量不同的编码。对于UWB SAW标签，在阅读器辐射功率低至<0.1毫瓦且占空比极低的情况下，估计读取范围约为2米。
