Document Type and Number:
WIPO Patent Application WO/2019/065496
Kind Code:
A1
Abstract:
An antenna device 100 comprises a magnetic body core 1 having a first main surface and a second main surface and extending in a first direction, a planar-shaped first coil 2, and a planar-shaped second coil 3 that is connected in series to the first coil 2 and is disposed in a line with the first coil 2 along the first direction. The first coil 2 has: a first portion 21 positioned on the first-main-surface side of the magnetic body core 1; and a second portion 22 positioned on the second-main-surface side of the magnetic body core 1, the second portion 22 being disposed in a position not overlapping the first portion 21 in plan view. The second coil 3 has: a third portion 31 positioned on the first-main-surface side of the magnetic body core 1; and a fourth portion 32 positioned on the second-main-surface side of the magnetic body core 1, the fourth portion 32 being disposed in a position not overlapping the third portion 31 in plan view. The minimum distance between the second portion 22 and the fourth portion 32 is less than the minimum distance between the second portion 22 and the third portion 31. A multiaxial antenna device includes a plurality of antenna devices including the antenna device 100.
