    摘要: This disclosure provides systems, methods and apparatus for wireless power transfer using resonant ferrite antennas to transmit and receive power. Ferrite structures concentrate magnetic flux lines into the structure, thereby creating a magnetic path and field with less interference and eddy current losses than in device electronics, thereby improving the efficiency of magnetic power distribution. The disclosure describes tuning the resonance frequency by mechanically adjusting the position of the coil on the rod. The ferrite rod antennas described herein may be used to transfer power to handheld communication devices.
