在这篇文章中，我们提出了一种一维定位技术，使用混合电感电容耦合平行线馈线，适用于室内工业应用。所提出的系统使得标签能够通过感测沿着细长馈线的驻波图案来检测其自身的位置。如果标签仅通过电感耦合测量磁场，则该方法的可检测范围被限制为大约四分之一波长，因为磁场强度重复超过该距离。为了增加检测范围，我们使用特殊的耦合器来观察电场和磁场的驻波图案，并将其与参考图案进行比较。仿真和实验结果表明，该方法能够在约半波长范围内进行定位。2019年日本电气工程师协会出版社：John Wiley & Sons，Inc.
In this article, we propose a one‐dimensional positioning technique using hybrid inductively–capacitively coupled parallel line feeder, suitable for indoor industrial applications. The proposed system enables a tag to detect its own position by sensing the standing wave pattern along the elongated feeder. If the tag measures only the magnetic field via inductive coupling, the detectable range of this approach is limited to approximately a quarter wavelength as the magnetic field strength repeats beyond this distance. To increase the detectable range, we use a special coupler to observe the standing wave patterns of both electric and magnetic fields and compare them with the reference patterns. Simulation and experiment results show that our method is capable of positioning in approximately a half wavelength. © 2019 Institute of Electrical Engineers of Japan.
