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.
