由于当今射频识别(RFID)的广泛使用,已经出现了关于无源RFID标签的定位技术的应用。到目前为止,大多数方法提供低定位精度,并需要移动部件(机械天线转向),这限制了它们的应用。在这里,我们介绍了一个RFID标签定位系统,利用有源电子操纵阵列,其中的定位方法是基于雷达系统的原理。我们彻底介绍了系统的主要属性与有限元(有限元法)仿真模型的帮助下,并调查系统的性能与远场测试。在移动的机器人定位和包装货物的自动化处理等应用中,所展示的定位精度小于40 mm。
Thanks to the nowadays widespread use of radio frequency identification (RFID), applications have emerged concerning positioning techniques for passive RFID tags. Most of the approaches so far deliver low positioning precision and require moving parts (mechanical antenna steering), which limits their application. Herein, we introduce an RFID tag positioning system utilizing an active electronically-steered array, where the positioning methodology is based on the principles of radar systems. We thoroughly present the main attributes of the system with the aid of an FEM (finite element method) simulation model and investigate the system performance with far-field tests. The demonstrated positing precision of less than 40 mm can be helpful in applications like mobile robot localization and the automated handling of packaged goods.
