Multiresonator based chipless RFID tag and dedicated RFID reader

A RFID system with a chipless RFID tag on a 90-µm thin Taconic TF290 laminate is presented. The chipless tag encodes data into the spectral signature in both magnitude and phase of the spectrum. The design and operation of a prototype RFID reader is also presented. The RFID reader operates between 5 – 10.7 GHz frequency band and successfully detects a chipless tag at 15 cm range. The tag design can be transferred easily to plastic and paper, making it suitable for mass deployment for low cost items and has the potential to replace trillions of barcodes printed each year. The RFID reader is suitable for mounting over conveyor belt systems.
