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.
