Electronic device including coil

A portable communication device is provided. The portable communication device includes near field communication (NFC) circuitry; wireless charging circuitry; magnetic secure transmission (MST) circuitry; a flexible printed circuit board (FPCB) including a first substrate layer and a second substrate layer; an NFC coil electrically connected with the NFC circuitry, the NFC coil including a first portion formed on the first substrate layer and a second portion formed on the second substrate layer; a wireless charging coil electrically connected with the wireless charging circuitry, the wireless charging coil including a third portion formed on the first substrate layer and a fourth portion formed on the second substrate layer; and an MST coil electrically connected with the MST circuitry, the MST coil including a fifth portion formed on the first substrate layer and a sixth portion formed on the second substrate layer.

An electronic device is provided. The electronic device includes a housing; a plurality of coils that are disposed on a first layer within the housing; a plurality of other coils disposed on a second layer substantially parallel to the first layer; a first conductor that connects an end point of a first coil of the plurality of coils and a start point of a second coil of the plurality of other coils and conducts a current from the end point of the first coil to the start point of the second coil; and a second conductor that connects a start point of a third coil adjacent to an outer side of the first coil of the plurality of coils and an end point of the second coil and conducts the current to be applied from the end point of the second coil to the start point of the third coil, wherein the first conductor and the second conductor induce a directional magnetic field when the current flows.

An electronic device and a method of operating the electronic device are provided. The electronic device includes a communication circuit; a battery; a first conductive pattern electrically connected to the battery and configured to wirelessly receive power; a second conductive pattern electrically connected to the communication circuit; a processor; and a memory that stores instructions, which when executed, instruct the processor to receive power from an external device through the first conductive pattern, to detect a voltage or a current of a signal output from the second conductive pattern while receiving the power, and to provide an output that is at least partially based on the detected voltage or current of the signal output from the second conductive pattern.
