A novel resonator for simultaneous Wireless Power Tranfer and Near Field Magnetic Communications

On one hand resonant Wireless Power Transfer (WPT) can be realized by using resonant coils coupled via their magnetic fields; on the other hand Near-Field Magnetic Communications (NFMC) are currently receiving considerable attention for several possible applications. We present a novel structure that can be used for both WPT and NFMC; this structure shows a dual band transmission channel allowing a frequency separation of the power channel and of the data channel, thus enabling simultaneous transmission of power and data. A test system is designed, simulated and measured to show the effectiveness of the proposed structure.
