1. An electronic device comprising:

  • wireless power antenna circuitry;

    a power supply configured to supply direct current (DC) power;

    a conversion circuit;

    a communication unit; and

    a controller configured to;

    receive, through the communication unit, a signal from an external electronic device;

    identify a wireless power scheme based on a type of the received signal, the wireless power scheme comprising one from among a first wireless power scheme and a second wireless power scheme;

    select one from among a transmission mode and a reception mode based on the received signal; and

    identify a wireless power frequency corresponding to the wireless power scheme,wherein the wireless power antenna circuitry comprises;

    first wireless power antenna circuitry corresponding to the first wireless power scheme and connected to the conversion circuit, andsecond wireless power antenna circuitry corresponding to the second wireless power scheme and connected to the conversion circuit,wherein the first wireless power antenna circuitry is electrically connected in parallel to the second wireless power antenna circuitry, andwherein the controller, in response to the transmission mode being selected, is further configured to;

    control the conversion circuit to convert the DC power to alternating current (AC) power using the wireless power frequency, andtransmit, through the wireless power antenna circuitry, the AC power to the external electronic device,wherein the first wireless power antenna circuitry is electrically connected between a first connection point and a second connection point of the conversion circuit, andthe second wireless power antenna circuitry is electrically connected to the first connection point via a first capacitor and to the second connection point via a second capacitor.
