Abstract
The invention provides a power supplying device, which includes a first coil; and a second coil, which is wound to be substantially line symmetrical to the first coil with respect to a center line, wherein the center line is an axis passing through a winding center of the first coil. A ground point of the first coil and the second coil is disposed further inside than an outermost winding of the first coil.
Claims17
A power supplying device, comprising:
- a first coil;
- and
- a second coil, wound to be substantially line symmetrical to the first coil with respect to a center line, wherein the center line is an axis passing through a winding center of the first coil,
- wherein a ground point of the first coil and a ground point of the second coil being provided further inside than an innermost winding of the first coil, and
- wherein a first connecting line connects the ground point of the first coil to the ground point and a second connecting line connects the ground point of the second coil to the ground point,
- wherein the first coil, the second coil and the ground point of the first coil and the ground point of the second coil are provided on a substrate having multiple layers,
- wherein the substrate comprises an electric field shielding layer, and
- the electric field shielding layer is connected to the ground point of the first coil and the ground point of the second coil are and formed to show a substantial line symmetry with respect the axis as the center line.
