RFID radio channel performance analysis

摘要

RFID applied to vehicular identification operates under a complex electromagnetic environment; the radio waves emitted by the reader, propagate, attenuate and join to the reflected waves from the ground and adjacent vehicles, being received by the antenna tag; part of the electromagnetic wave signal is backscattered/reflected back to the reader. In order to obtain a propagation model is carried a deterministic and statistical radio channel analysis out, in such a way that the signal performance could be predictable in an outdoor environment. RFID radio channel multipath environment analysis is the focus of this work.
