Abstract
An electronic device includes a resonance coil forming at least one loop and configured to resonate at a specific frequency. A feeding coil forms at least one loop, is physically separated from the resonance coil, and is located in proximity to the resonance coil to enable electromagnetic coupling with the resonance coil. A communication circuit is electrically connected to the feeding coil and configured to generate an electric signal of the specific frequency.
