摘要： An electronic device for supporting power sharing and data communication with an external electronic device, and a method therefor are provided. The electronic device includes a power management circuit, an antenna including a first coil and a second coil, a transceiver circuit configured to transmit a power signal received from the power management circuit to the antenna and to transmit a power signal received from the antenna to the power management circuit, the transceiver circuit including a first transceiver terminal and a second transceiver terminal, a first switch, and a control circuit electrically connected to the first switch and the transceiver circuit. A first end of the second coil may be connected to the first transceiver terminal. A second end of the second coil may be connected to the second transceiver terminal. A first end of the first coil may be connected to the first transceiver terminal through the first switch. A second end of the first coil may be connected to the second transceiver terminal. The control circuit may be configured to control the first switch based on identification information of an external electronic device received from the antenna through the transceiver circuit.
