Measurements of Frequency Splitting Phenomenon in Resonant Wireless Power Transfer System of Inductively Fed Antennas

In this paper, we observe the frequency splitting phenomenon in four-coil resonant wireless power transfer systems. First, a simple approach for easy setup of the inductively fed antennas in the mode of the resonant transformer is proposed. Then, the system is simulated in 4 nec 2 software, manufactured, and finally set and measured by a vector network analyzer. An experiment with wireless light is shown for the illustration.
