Abstract :
Recently, an electromagnetic radiation decoupler with significant advantages (low profile and simple structure) was proposed for metallic item detection in UHF RFID systems. In this paper the decoupler is investigated by simulation and experiment. Based on the simulation, some new design principles, different from the original principles of the inventors, aimed at optimizing the performance of the decoupler, are proposed. These new design principles are verified by measurement.
