1. A communication device using wireless power, the communication device comprising:
- a controller configured to determine whether a mutual resonance occurs between a target resonator and a source resonator in a symbol duration; and
a modulator configured to modulate data, based on whether the mutual resonance occurs;
a charger configured to charge an inductor and a capacitor using power through the mutual resonance;
a power delivering unit configured to deliver power stored in the capacitor to a load; and
a switch controller configured to control a switch that connects the capacitor to the charger or to the power delivering unit, based on a determination of the controller,wherein the target resonator includes the inductor and the capacitor.
