Abstract :
Five-port architectures are investigated as a reflectometer for adaptive load impedance matching. The proposed reflectometer requires computationally simple control loop. Moreover, the adaptive load impedance matching system in RFID UHF band are proposed. Using simulation and measurement studies, it is shown that the five-port architecture can be used as a low-cost, simple and high-performance reflectometer in adaptive load matching systems.
