17. A wireless energy transfer device, comprising:
-
a power transmission unit that generates an oscillating magnetic field or oscillating electric field; a power reception unit, which is provided with a receiving antenna, and which converts the oscillating magnetic field or the oscillating electric field of the power transmission unit to electric power with the receiving antenna; and an electric power theft suppression unit that suppresses a theft of energy with the oscillating magnetic field or the oscillating electric field of the power transmission unit, wherein the electric power theft suppression unit comprises;
a frequency changing unit that changes a frequency of the oscillating magnetic field or the oscillating electric field generated by the power transmission unit; and
a first resonance frequency changing unit that changes a resonance frequency of the receiving antenna according to the change in the frequency of the oscillating magnetic field or the oscillating electric field. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32)
