A fully passive 12-Bit multi-resonator based printable chipless RFID system is presented in this work. It focuses on the difficulties of achieving low-cost chip RFID systems. The emergence of chipless RFID systems would be a cheaper solution in the present scenario for low-cost item tracking. The proposed multi-resonator based chipless RFID tag and reader, along with their requirements, and specifications, are specified. By considering the 12-bit encoder, the working and design of the RFID system and its components, such as resonators and antennas, are detailed. © 2021 IEEE.
