项目摘要

Despite intensive research worldwide into chipless RFID in recent years and despite the many potential benefits of the technology, such as zero maintenance requirements and high level of robustness, no sustainable chipless RFID concepts have as yet emerged. The only applications of any significance have been surface acoustic wave RFID tags and basic 1-bit tags for electronic article surveillance. To overcome these limitations, the applicant recently proposed polarimetrically coded radar barcodes as a completely new concept for chipless RFID. A polarimetrically coded radar barcode is a two-dimensional array of partial reflectors each with their own characteristic polarimetric response. A polarimetric imaging radar reads the information stored on the tag remotely. In preliminary research it was shown that the novel approach has the potential to achieve chipless RFIDs with a data capacity of more than 1,000 bits and tag operating temperatures well above 1,000°C. Fundamental research on the design and assessment of polarimetrically coded tags is at the heart of this project. Among the main research elements are coding techniques, designing appropriate reflector structures as well as arranging the structures on the tag in an optimal manner. A key objective of all design considerations is to identify and assess the effects of faults and interference issues on data capacity and detection reliability during the reading process. The impact of tag rotation and tilt and the compensation of these effects will be investigated as well. The system variants previously demonstrates in the preliminary research required artificial, well defined tag / reader arrangements that are impractical for realistic application scenarios. Thus, the overall design goals are: firstly to maximize the data capacity on as small a surface area as possible with efficient design and manufacturing processes and secondly to overcome the above mentioned restrictions in respect to the reading conditions. All these studies relating to the tag and the system concept will provide a comprehensive insight into this novel chipless RFID technology and its potential and limitations. As leading-edge applications and as proof of performance of this innovative technology we will design and experimentally demonstrate chipless RFID tags with a data capacity of more than 1,000 bits as well as tags reaching operating temperatures above 1,000°C under varying reading conditions that are representative for potential practical application scenarios. This project is a major step forward for chipless tag technology in relation to data capacity and to robustness against extreme temperatures. We anticipate that this disruptive technology will break new ground in a range of applications, applications that heretofore could not be pursued with current RFID technologies.

尽管近年来全世界对无芯片RFID进行了深入的研究，并希望该技术的许多潜在好处，例如零维护要求和高水平的鲁棒性，但尚未出现可持续的无芯片RFID概念。任何意义上的唯一应用是表面声波RFID标签和电子文章监视的基本1位标签。为了克服这些局限性，最近提议的极化编码雷达条形码是无芯片RFID的全新概念。极化编码的雷达条形码是二维反射器的二维阵列，每个反射器都具有自己的特征偏振响应。极化成像雷达读取远程存储在标签上的信息。在初步研究中，这表明这种新方法具有实现具有超过1,000位的数据容量和TAG操作温度远高于1,000°C的无芯片RFID。关于偏振版标签的设计和评估的基本研究是该项目的核心。主要研究元素包括编码技术，设计适当的反射器结构以及以最佳方式安排标签上的结构。所有设计考虑因素的关键目的是识别和评估错误和干扰问题对阅读过程中数据容量和检测可靠性的影响。标签旋转和倾斜的影响以及这些效果的补偿也将得到研究。先前在初步研究中证明的系统变体所需的人工，定义明确的标签 /读取器布置，对于现实的应用程序场景是不切实际的。这就是总体设计目标：首先，通过有效的设计和制造过程，最大程度地提高表面积的数据容量，其次是克服有关阅读条件的上述限制。与标签和系统概念有关的所有这些研究都将为这种新颖的无芯片RFID技术及其潜力和局限性提供全面的见解。作为领先的应用和作为这种创新技术的性能证明，我们将设计和实验证明具有超过1,000位数据容量的无芯片RFID标签，以及在不同的阅读条件下达到1,000°C以上的工作温度的标签，这是代表潜在实用应用程序的代表性。对于数据容量和防御极端温度的鲁棒性，该项目是芯片标签技术的重要一步。我们预计，这种破坏性的技术将在一系列应用程序中打破新的基础，而当前的RFID技术无法追求这些应用程序。
