Beschreibung
This book examines the design of chipless RFID systems. The authors begin with the historical development of wireless identification systems and finally arrive at a representation of the chipless RFID system as a block diagram illustration. Chapter 2 is devoted to the theoretical bases for the design of chipless RFID tags and detection techniques in the reader. A rigorous mathematical formulation is presented based on the singularity expansion method (SEM) and characteristic mode theory (CMT) in order to study the scattered fields from an object in a general form. Th e authors attempt to explain some physical concepts behind the mathematical descriptions of the theories in this chapter. In Chapter 3, two design procedures based on complex natural resonance and CMT are presented for the design of the chipless RFID tag. By studying the effects of structural parameters on radiation and resonant behaviors of the tag, some design conclusions are presented in this chapter. Chapter 4 is dedicated to the time-frequency analysis of the scattered fields from chipless RFID tags. After some explanation of the time-frequency analysis techniques and issues relating to resolution in time and frequency, an efficient technique called short-time matrix pencil method (STMPM) is introduced and efficiently employed to study various scattering mechanisms. Th e performance of the proposed technique against noise is studied in this chapter. Finally in Chapter 5, an anti-collision algorithm is presented through which the positions and IDs of multiple multi-bit tags are extracted from the backscattered signal of the tags present in the reader area.
This book examines the design of chipless RFID systems. The authors begin with the philosophy of RFID and its effect on commercial applications. Then, they discuss the chipless RFID systems and the application of chipless RFID systems, the advantages it provides compared to conventional barcode ID and chipped RFID tags. The text then covers chipless RFID components in block diagram representation and introduce FCC requirements which should be considered in the design procedure of each component. The third chapter is dedicated to the complex natural resonance-based design of chipless RFID tags. The next chapter concerns about the detection techniques introduced for the identification of chipless RFID tags. The fifth chapter is dedicated to the localization and anti-collision techniques in chipless RFID systems. Final chapter is chipless RFID tags as sensors. It provides some applications where the tag can be used as both ID and sensor. The tag specifications and detection issues are addressed in this section.
Provides simulation tools and measurement setups and presents numerical and experimental results to confirm the theoretical formulations Discusses MATLAB codes at the end of each chapter to allow the readers to simulate the results Presents theoretical issues for detection Includes supplementary material: sn.pub/extras
