Chipless Radio Frequency Identification (RFID) Systems for Mineral Characterisation

Mineral characterisation is essential in the mining industry for effective resource management. However, existing sensing technologies are often expensive, bulky, and performance-limited. This research explored chipless radio frequency identification (RFID) technology as a cost-effective, compact, and efficient alternative for mineral characterisation. Innovative sensor designs were created to improve accuracy and reliability. Furthermore, a field-programmable gate array (FPGA)-based impulse radio ultra-wideband (IR-UWB) reader was developed for rapid and economical signal processing. These advancements demonstrate how chipless RFID can offer a viable solution for mineral analysis, ultimately leading to more efficient and sustainable mining operations.
