Design and Optimization of Passive UHF RFID Systems | Jari ...
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....

Active RFID versus passive RFID | RFID4U
Requires presence of interrogator to work
Limited amount data storage
Require higher power interrogators
Low read range (few inches to 20 feet)
Note: A low read range might be considered an advantage or a disadvantage, depending on a tag's application. When a tag is used for credit card or for access control card, a low read range is an advantage, because you do not want somebody to be able to...

The vector differential RCS of an RFID tag as seen by the reader is analysed and, for the first time, compared with experimental results in UHF band. Introduction: Radio frequency identification (RFID) can be traced back to the late 1940's work on using RF modulated backscatter for communications [1]. Fig. 1 illustrates the operation of a modern passive RFID system which includes an RFID reader and an RFID tag, composed of an antenna and an integrated circuit chip. The reader signal alternates between a continuous wave (CW) and modulated transmissions. The tag sends data during...
