Abstract
Provided is a portable device. The portable device includes a near distance antenna, a long distance antenna, a first power generation circuit, a second power generation circuit, and a battery. The near distance antenna receives a first power source signal in an electromagnetic inductive coupling scheme. The long distance antenna receives a second power source signal in a magnetic resonance scheme. The first power generation circuit generates a power source from the first power source signal. The second power generation circuit generates a power source from the second power source signal. The battery is charged with the generated power source.
