Improving RFID tag detection in the presence of mechanical vibration

This paper discusses the mechanical vibration effect of metal structure on RFID and presents a solution to circumvent it. The transmission link between a tag and RFID reader is affected by induced current issued from magnetic coupling. This interference affects mainly the performances of the RFID reader. A new practical technique that avoids the resulting coupling interference is presented in this paper. The RFID system is analyzed at low frequency to provide a new solution that answers to the requirements of industrial applications according to ISO standards. The RFID reader´s antenna is accurately simulated with EMWorks software under different environment magnetic conditions in order to identify the main source of interference problem. Experimental results validate the solution presented in this paper and prove its enhanced performances.
