Document Type and Number:
WIPO Patent Application WO/2023/098170
Kind Code:
A1
Abstract:
Provided in the present application are a wireless charging coil, an electronic device including a wireless charging coil, and an antenna. The wireless charging coil comprises layers of a plurality of coil groups, which are connected in series, and an insulating layer, which is located between two layers of the plurality of coil groups. The wireless charging coil comprises a first area, and a second area which is located on the periphery of the first area. The plurality of coil groups located in the second area are arranged in a plurality of layers, and each coil group comprises a plurality of coils which are wound in one layer in parallel. With regard to the coil group in the first area with a non-uniform current distribution, a plurality of coils are distributed, in parallel, in a plurality of layers, such that the current density in the coils of the first area is dispersed in a plurality of layers, thereby improving the uniformity of the current distribution.
