說(shuō)明書(shū)
According to an embodiment, the coil unit 200 may include a designated first coil 210 by a first number of turns and a designated second coil 220 by a second number of turns. The first coil 210 includes a wire implemented in a helical form in which a plurality of layers are stacked and arranged, and may be implemented in the form of a part of at least one of a circle, an ellipse, or a polygon. The first coil 210 may be provided in the form in which an opening is provided in the inner center thereof, and a wire (e.g., a power transmission circuit 500) extending from the inner diameter end and/or the outer diameter end thereof may be electrically connected to the circuit board 400.
According to an embodiment, the second coil 220 may include at least one layer, and may be coplanar with at least one layer of the first coil 210. The second coil 220 may include a conductive wire in a helical form, and may be implemented as a part of at least one of a circle, an ellipse, or a polygon. The second coil 220 may be provided in the form in which an opening is provided in the inner center thereof, and a wire (e.g., a power transmission circuit 500) extending from the inner diameter end and/or the outer diameter end thereof may be electrically connected to the circuit board 400.
