Title:
PLANAR COIL
Document Type and Number:
WIPO Patent Application WO/2024/029835
Kind Code:
A1
Abstract:
The present specification relates to a planar coil. The planar coil according to an embodiment may comprise: a substrate; and a conductor layer disposed at at least one of a first surface and a second surface of the substrate and including a plurality of conductor tracks. In an embodiment, the respective conductor tracks may be arranged at different arrangement intervals. In an embodiment, the respective conductor tracks may have different widths. If an AC current is supplied to the planar coil according to embodiments of the present specification, the intensity of a magnetic field formed around the planar coil is increased and the magnetic flux density thereof is enhanced. Accordingly, the performance of devices using electromagnetic induction through the planar coil can be improved.
