Meanwhile, the power reception circuit 451 of the wireless power reception device 21 or 22 according to an embodiment may receive power from the power transmission circuit 411 of the electronic device 10. The power reception circuit 451 may be implemented in the form of an embedded battery, or may be implemented in the form of a power reception interface so as to receive power from the outside. The power reception circuit 451 may include a loop coil 451L made of a conductive pattern. The power reception circuit 451 may receive, through the loop coil 451L, the wireless power in the form of electromagnetic waves generated in response to the current/voltage applied to the loop coil 411L of the power transmission circuit 411. For example, the power reception circuit 451 may receive the power that is supplied from the power transmission circuit 411 to the loop coil 451L of the adjacent power reception circuit 451 as the power in the form of an AC waveform, which is applied to the loop coil 411L of the power transmission circuit 411, generates an induced electromotive force. For example, the power reception circuit 451 may receive, through the loop coil 451L, the wireless power in the form of electromagnetic waves generated in response to the current/voltage applied to the loop coil 411L of the power transmission circuit 411.
The power reception circuit 451 may further include, for example, a matching circuit 451a, a rectifying circuit 451b, a regulation circuit (regulator) 451c, a switch circuit 451d, and a battery 451e, in addition to the loop coil 451L.
