This book presents a step-by-step discussion of the Design and Development of Radio Frequency Identification (RFID) and RFID-enabled Sensors on Flexible Low Cost Substrates for the UHF Frequency bands. Various examples of fully function building blocks (design and fabrication of antennas, integration with ICs and microcontrollers, power sources, as well as inkjet-printing techniques) demonstrate the revolutionary effect of this approach in low cost RFID and RFID-enabled sensors fields. This approach could be easily extended to other microwave and wireless applications as well. The first chapter describes the basic functionality and the physical and IT-related principles underlying RFID and sensors technology. Chapter two explains in detail inkjet-printing technology providing the characterization of the conductive ink, which consists of nano-silver-particles, while highlighting the importance of this technology as a fast and simple fabrication technique especially on flexible organic substrates such as Liquid Crystal Polymer (LCP) or paper-based substrates. Chapter three demonstrates several compact inkjet-printed UHF RFID antennas using antenna matching techniques to match IC's complex impedance as prototypes to provide the proof of concept of this technology. Chapter four discusses the benefits of using conformal magnetic material as a substrate for miniaturized high-frequency circuit applications. In addition, in Chapter five, the authors also touch up the state-of-the-art area of fully-integrated wireless sensor modules on organic substrates and show the first ever 2D sensor integration with an RFID tag module on paper, as well as the possibility of 3D multilayer paper-based RF/microwave structures. The authors would like to express our gratitude to the individuals and organizations that helped in one way or another to produce this book. First to the colleagues in ATHENA research group in Georgia Institute of Technology, for their contribution in the research projects. To the staff members in Georgia Electronic Design Center, for their valuable help. To Jiexin Li, for her continuous support and patience.To Amir Mortazawi, our series editor, for his guidance. Also, the book would not have been developed without the very capable assistance from Joel D. Claypool, and other publishing professionals at Morgan & Claypool Publishers.
