According to various embodiments of the present disclosure, an electronic device may include a housing, a conductive pattern that is arranged within the housing and is formed to generate a magnetic field, a plate that forms at least a part of a first surface of the housing and includes a material that at least partially transmits the magnetic field generated by the conductive pattern, and a communication circuit that is configured to transmit at least one transaction information to an external device by using the conductive pattern. The conductive pattern may include a first end that is electrically connected to the communication circuit, a second end that is electrically connected to the communication circuit, and a coil that is connected between the first end and the second end and includes a plurality of turns that are substantially parallel to a surface of the plate.

Electronic device and transaction method using the same

Disclosed are various embodiments related to an electronic device including a coil. The electronic device may include: a housing including a first face facing a first direction and a second face facing a second direction different from the first direction; and a flexible printed circuit board and a control circuit disposed between the first and second faces. The flexible printed circuit board may include a first coil including at least one turn, a second coil including at least one turn, and a third coil including at least one turn. At least a part of the second coil may surround a first portion of the first coil, a second portion of the first coil may surround at least a part of the second coil, a third portion of the first coil may surround the second portion of the first coil, and at least a part of the third coil may be disposed between at least a part of the second portion of the first coil and at least a part of the third portion of the first coil. The control circuit may be configured to: transmit a signal outward by a first transmission method using the first coil; transmit a signal outward by a second transmission method using the second coil; and transmit a signal outward by a third transmission method using the third coil.

Electronic device including multiple coils

An electronic device, of the present disclosure, may include: a housing; an antenna unit disposed inside the housing and including a conductive pattern configured to generate a magnetic field; a plate comprising at least a part of the housing and including a material through which at least a part of the magnetic field generated by the conductive pattern can pass; and a control circuit configured to transmit at least one piece of payment information to an external device using the conductive pattern, wherein the antenna unit including the conductive pattern includes: a first coil having a first plurality of turns that is substantially perpendicular to one surface of the plate; and a second coil having a second plurality of turns that is substantially parallel to the surface of the plate, and a shielding structure comprising a shielding material is disposed inside the first coil or below the second coil. The electronic device, according to various example embodiments of the present disclosure, can implement various read-out methods (for example, a Near Field Communication (NFC) method and a Magnetic Secure Transmission (MST) method) with one module due to the shape of the shielding structure disposed in the antenna unit.

Electronic device including shielding structure

An electronic device including a proximity recognition module configured to recognize second electronic device proximate to the first electronic device, a communication module configured to wirelessly transmit and receive data to and from the second electronic device, and a power supply module configured to apply at least one of power charged in the first electronic device and power wirelessly supplied from the second device as power for the communication module, based on the recognition with respect to the second device. Other embodiments are also possible.
