Investigation of Chipless RFID Tag Performance in Coal Mining Conveyor Belt

Abstract

Chipless RFID tags can be used as sensors to monitor the health of coal transporting conveyor belts. However, the proximity to different dielectric materials of the conveyor belt‘s structure influences the sensor behavior dramatically. In this paper, the effect of a practical belt's composition layers with varying dielectric properties on a chipless tag is investigated. The significant change in the tag‘s resonant frequency and notch depth demonstrates the prominence of material properties on tag response. This investigation would help to improve the system modelling and sensor‘s performance when the chipless RFID sensors are embedded in coal mining conveyor belt.
