Abstract
Disclosed herein is a coil component that includes a first coil, and a second coil disposed so as to surround the first coil. The first coil includes a first section extending in a first direction, a second section extending in a second direction orthogonal to the first direction, and a third section positioned between the first and second sections. Gaps between the first, second, and third sections of the first coil and the second coil as viewed in a coil axis direction have a first width, a second width, and a third width, respectively. The second width is larger than the first width and smaller than the third width.
Claims8
A coil component comprising:
- a first coil;
- a second coil disposed so as to surround the first coil;
- and
- a substrate on which the first coil and the second coil are formed,
- wherein the first coil includes a first section extending in a first direction, a second section extending in a second direction orthogonal to the first direction, and a third section positioned between the first and second sections,
- wherein gaps between the first, second, and third sections of the first coil and the second coil as viewed in a coil axis direction have a first width, a second width, and a third width, respectively,
- wherein the second width is larger than the first width and smaller than the third width,
- wherein the second coil includes a first coil pattern provided on one surface of the substrate and a second coil pattern provided on other surface of the substrate, and
- wherein the first coil pattern and the second coil pattern have a section overlapping each other in the coil axis direction and another section not overlapping each other in the coil axis direction.
A wireless power transmission device comprising:
- a coil component comprising i) a first coil, ii) a second coil disposed so as to surround the first coil, and iii) a substrate on which the first coil and the second coil are formed;
- a power transmission circuit connected to the first coil;
- and
- a communication circuit connected to the second coil,
- wherein the first coil includes a first section extending in a first direction, a second section extending in a second direction orthogonal to the first direction, and a third section positioned between the first and second sections,
- wherein gaps between the first, second, and third sections of the first coil and the second coil as viewed in a coil axis direction have a first width, a second width, and a third width, respectively,
- wherein the second width is larger than the first width and smaller than the third width,
- wherein the second coil includes a first coil pattern provided on one surface of the substrate and a second coil pattern provided on other surface of the substrate, and
- wherein the first coil pattern and the second coil pattern have a section overlapping each other in the coil axis direction and another section not overlapping each other in the coil axis direction.
