Radio Frequency IDentification (RFID) stores and retrieves data using devices called RFID tags: objects attached to or incorporated into a product, animal or person which communicate with an RFID reader or interrogator. This book proposes a linear two-port model for an N-stage modified-Greinacher full wave rectifier, predicting the overall conversion efficiency at low power levels where the diodes are operating near their threshold voltage. Included is an experimental procedure to measure how impedance modulation in the tag affects the signal at the reader, and a useful tool for choosing the most appropriate impedances.

From the reviews:
"In this agile book of just 148 pages, the reader is introduced to the design of a passive RFID system operating in the UHF band. ... The book is a useful tool for the RFID UHF system designer, and can also be a valuable guide for the newcomer interested in understanding the multifaceted issues involved in the development of RFID and of its specifications." (S. Donati and T. Tambosso, Optics and Photonics News, July/August, 2007)
Radio Frequency Identification (RFID) is an automatic identification method, relying on storing and remotely retrieving data using devices called RFID tags or transponders. An RFID tag is an object that can be attached to or incorporated into a product, animal, or person for the purpose of identification using radio waves. Chip-based RFID tags contain silicon chips and antennas. Active tags require an internal power source, while passive tags do not.
Design and Optimization of UHF RFID Systems considers the analysis, design and optimization of UHF passive RFID systems for long-range applications. There are many key aspects thoroughly described in the text:
Wireless power transmission is studied using a rectifier (a fundamental tag building-block) for which there has been a proven prediction model developed. Proposed is a theoretical analysis of possible backscattering modulations, as well as an experimental procedure to measure how the impedance modulation at the tag side, affects the signal at the reader. Finally, a complete tag design achieving a read range of 12 m at 2.45 GHz (4 W EIRP) is provided. At the time of writing, the results of this design outperform any other available IC tag.
