Design of Stacked Tags for Mutual Impedance in Intensive Distribution Environment

摘要

摘要: 在密集布放环境中，超高频射频识别标签(UHF RFID)会受到相邻标签的干扰产生互阻抗，导致读取率下降。基于二端口网络和八木阵列天线的理论，该文分析天线结构与互阻抗的关系，并解释标签天线传输系数和增益的变化原因。进而提出一种密集布放环境中的标签互阻设计方法。仿真和测试结果表明，新标签不仅单一性能良好，且互相间的干扰小，适用于多标签密集布放环境中的射频识别系统。

Abstract: In the dense distribution environment, the Ultra-High Frequency Radio-Frequency IDentification (UHF RFID) tags are interfered by the mutual impedance of adjacent tags, which can lead to a decline in reading rate. Based on the two-port network and Yagi-Uda antenna array theory, this paper firstly analyzes the relationship of antenna structure and mutual impedance. Then, the reasons for the change of the tag antenna transmission coefficient and the gain are explained. At last, a design of stacked tags for mutual impedance in intensive distribution environment is proposed. The numerical simulation and measurement results show that the new kind of RFID tag, not only has better performance in stand-alone scenario, but also has less interference between each other. It is suitable for RFID system in dense environment of multiple tags.
