Title:
INDUCTOR AND PREPARATION METHOD THEREFOR, FILTER, AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/082210
Kind Code:
A1
Abstract:
The present disclosure relates to the technical field of passive devices, and provided thereby are an inductor, a preparation method therefor, a filter, and an electronic device. The inductor of the present disclosure comprises a dielectric substrate and N-turn coil structures arranged on the dielectric substrate. The N-turn coil structures are sequentially nested and electrically connected. N ≥ 2, and N is an integer. For any coil structure, the coil structure comprises a plurality of layers of sub-coils which are sequentially arranged on the dielectric substrate, and at least one interlayer insulating layer is arranged between adjacent sub-coils. Sub-coils of adjacent layers are electrically connected by means of a first connection via penetrating the interlayer insulation side therebetween.
