摘要

本文研究的是时间编码的无芯片RFID标签。这些标签由连接到延迟线的超宽带散射天线组成。本文介绍了它们的基本工作原理，解释了两种散射模式(结构模式和标签模式)的行为。标签的测量使用低成本的时域脉冲无线电超宽带雷达，该雷达扮演RFID阅读器的角色。标签的特征包括标签-结构模式比、读取范围、标签-读取器角度以及标签附着在材料上时对标签性能的影响。最后，讨论了时间编码无芯片标签实现完全无源无线传感器的潜力，并提出了未来的应用。

Time-coded chipless RFID tags: Design, characterization and application

This paper deals with time-coded chipless RFID tags. These tags consist of an ultra-wideband scattering antenna connected to a delay line. The paper introduces their basic theory of operation, explaining the behaviour of the two scattering modes (structural and tag modes). The tags are measured using a low-cost time-domain impulse-radio ultra-wideband radar which takes the role of the RFID reader. The tags are characterized in terms of tag-to-structural modes ratio, read range, tag-reader angle and the impact on the tags' performance when they are attached to materials. Finally, the potential of time-coded chipless tags to implement completely-passive wireless sensors is addressed and future applications are proposed.
