摘要

An electronic device is provided. The electronic device includes a coil unit, a power transmission circuit electrically connected to the coil unit, and a control circuit configured to wirelessly transmit power using the coil unit, and the coil unit may include a first coil. The first coil may include a first layer wound in a first shape by a first number of turns, and a second layer extending from the first layer and wound in a second shape by a second number of turns, and the second layer may be disposed above the first layer to overlap the first layer.

說(shuō)明書(shū)

According to an embodiment, the second coil 220 may be disposed on a shielding member (e.g., the shield member 300 in FIG. 2) of the electronic device 10. According to an embodiment, the second layer 212 of the first coil 210 may be disposed on the shielding member 300. For example, the second layer 212 of the first coil 210 and the third layer 221 of the second coil 220 may be substantially coplanar with each other. The third layer 221 may be provided has a flat helical coil having a single-layer structure.

According to various embodiments, the first shape of the first layer 211 of the first coil 210 may be a ring shape in which one wire is wound in a helical shape, and the second shape of the second layer 212 of the first coil 210 may be a ring shape in which one wire extending from the first layer 211 is wound in a helical shape and may have an area smaller than that of the first layer 211 wound in the ring shape. As another example, the third shape of the third layer 221 of the second coil 220 may be a ring shape in which one wire is wound in a helical shape, and the wire of the third layer 221 may have a diameter equal to or larger than the diameter of the wire of the first layer 211 and/or the diameter of the wire of the second layer 212.
