Chipless radio frequency identification (chipless-RFID) is an emerging disruptive wireless technology for identification, tracking and sensing. A chipless RFID tag does not contain an application specific integrated circuit (ASIC), hence the reader does all signal processing to read the tag. Chipless RFID tags are low-cost passive microwave/millimetre wave circuits where the information is stored in printable resonators and delay lines and typically implemented in flexible substrates such aspolymers and papers, like optical barcodes. In recent years, chipless RFID sensors that combine functional/smart materials and chipless RFID technology have been developed. This workshop reports the most recent advances in chipless RFID tagdesign, reader architecture, signal processing, chipless RFID sensors and their various emerging applications. This workshop also includes the review of the state-of-the-art chipless RFID with a particular focus on the future trends, novel and advanced technologies for identification and sensing devices design with 3D-printing and carbon nano-tube (CNT), novel encoding schemes and strategies such as high-impedance surfaces, synchronous tags, and alphabets, and emerging applications such as the Internet of things (IoT), 5G communications, autonomous vehicles, smart wearable systems, security and authentication.
