Low Cost Chipless RFID Systems

Abstract

This chapter presents a comprehensive overview and novel classification of chipless RFID tags that can be found in the market and reported in peer-reviewed conferences and journals. The problems of achieving low cost chipped RFID are presented along with the proposed solution of chipless RFID for lowering the price of the RFID tag. Two main chipless RFID tag groups are presented: time domain reflectometry-based chipless RFID and spectral signature-based chipless RFID. A comprehensive report on different chipless RFID tags with their pro’s and con’s is presented. Following the chipless RFID tag classification is a comprehensive classification of chipless RFID readers, which can be found on the market. A system-level view and architectural exploration of RFID readers is presented. The chapter is closed with the presentation of the proposed multiresonator-based chipless RFID tag and reader along with their requirements and specifications.
