Passive UHF RFID tag consists of a microchip attached to an antenna. Proper impedance
match between the antenna and the chip is crucial in RFID tag design. It directly influences RFID tag
performance characteristics such as the read range. It is known that an RFID microchip is a nonlinear load
whose complex impedance varies with the frequency and the input power
