Claim:
1. A communication device using wireless power, the communication device comprising: a transmitter configured to transmit, to a target resonator, energy stored in a source resonator through mutual resonance; an energy compensator configured to compensate for energy expended in the source resonator; a controller configured to control an electrical connection of a power input unit selectively providing energy to the source resonator, wherein the power input unit is configured to be electrically separated from the transmitter while the transmitter transmits the energy stored in the source resonator, and wherein the transmitter comprises a storage capacitor configured to store energy from an input voltage provided by the power input unit when the source resonator is in self resonance and configured to release energy to the target resonator when the source resonator and the target resonator are in mutual resonance and the electrical connection is broken.
