Abstract

The recent widespread diffusion of radio-frequency identification (RFID) applications operating in the UHF band have been supported by both the request for greater interrogation ranges and larger and faster data exchange. UHF-RFID systems, exploiting a physical interaction based on Electromagnetic propagation, introduce many problems that have not been explored (or only partially) for the previous generations of RFID systems (e.g. HF). Therefore, the availability of reliable tools for modelling and evaluating the radio-communication between Reader and Tag within an RFID radio-link are needed. The paper discuss the impact of real environment (e.g. Electromagnetic Coupling, Multipath propagation) on system performance in terms of error-probability and received powers, showing some relevant effects and trade-offs in transponder and reader design.
