该论文设计了一种远程供电的RFID标签，采用脉冲超宽带（I-UWB）技术实现10Mb/s的上行数据率，并达到-18.5dBm灵敏度的UHF下行链路，解决了现有被动RFID标签数据率低和定位精度差的问题。
highly demanded, in future and emerging RFID technology [1]. The data rate of existing passive RFID tags is limited to a few hundreds of kb/s causing large latency. On the other hand, the position accuracy is not better than 70cm [2]. In an advanced design, a 3.4Mb/s data rate has been achieved in proximity operation [3]. Active tags with a narrowband radio link overcome these weaknesses, but, they are battery powered and more expensive. Impulse Ultra wideband (I-UWB) techniques using short pulses for data transmission has been recognized as a powerful candidate for future RFID systems. It has the possibility of achieving MB/s throughput, operating range of several tens of meters, centimeter positioning, low power consumption, and low
