In recent years, radio frequency identification (RFID) technology has been employed in mainstream applications for asset management, storage of goods, security, transportation and logistics. The RFID sensor has features which can revolutionize the field of automated object identification in conjunction with condition monitoring. In this research, a novel chipless RFID sensor platform is proposed for wireless sensing of tagged objects. Since the proposed chipless RFID sensor does not require any on-board micro-chip and power source, it has great potential for low-cost, maintenance-free, automated and robust applications. The aim of this research is to develop single node multi-parameter sensing chipless RFID sensors in versatile RF sensing applications.
