Abstract :
Rapid growth of the application of the radio frequency identification (RFID) technology to object identification has lead to a demand for compact, reliable and inexpensive RFID tags of good read range. Matching between tag antenna and chip impedances for maximum power transfer then becomes very important. Constraints on impedance matching in tags that derive from the reactive elements of the chip and antenna impedances are investigated. Following the analysis, a successful small UHF RFID tag design is presented.
