1. A wireless power reception apparatus comprising:
a first electrode including a coil shape;
a second electrode including the coil shape;
an electrode capacitor connected between the first electrode and the second electrode;
an electrode signal transceiver connected to the first electrode and the second electrode;
a power receiver connected to the first electrode and the second electrode, separately from the electrode signal transceiver;
a resonant capacitor; and
a first capacitor and a second capacitor configured to selectively connect or disconnect a conducting line between the first electrode and the power receiver and a conducting line between the second electrode and the power receiver, depending on a selected frequency,
wherein the first electrode and the second electrode are wound in a same direction and are configured to form a single coil in response to the electrode capacitor being shorted.
