Title:
INDUCTOR ELEMENT, INDUCTOR BRIDGE AND HIGH-FREQUENCY FILTER
Document Type and Number:
WIPO Patent Application WO/2014/171266
Kind Code:
A1
Abstract:
Two coils formed by conductor patterns are placed beside each other on the same surface of an insulating substrate, are serially connected, and the winding direction and connection relationship of each coil are defined so that a linked flux of coils adjacent in the planar direction forms a loop. The insulating substrate is bent so that, the minor angle between a coil and the coil adjacent in the planar direction thereto is within the range from 180° to 90°. As a result, an inductor element is provided in which there is little change in characteristics because of bending, of which the direct current resistance is low despite the inductor element being small and thin, and of which the self-resonant frequency is high. Also provided are an inductor bridge provided with the same, and a high-frequency filter.
