Abstract
The recent widespread diffusion of radio-frequency identification (RFID) applications operating in the UHF band has been supported by both the request for greater interrogation ranges and greater 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 modeling 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 errorprobability and received powers, showing some relI documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
