Coding Using Chipless RFID Tags
摘要
This chapter presents the main types of chipless RFID tags, categorized by their coding principles. It covers the working principles, performance metrics, and examples of frequency-coded (FC), time-coded (TC), hybrid, image-based, motion-modulation, and near-field chipless tags. The chapter also discusses important figures of merit for tag design, such as radar cross section (RCS) and quality factor (Q), offering a detailed examination of these tag technologies.
