1. A coil comprising:
a first conductor disposed on a first plane and having a first end and a second end;
a second conductor having a third end and a fourth end and being disposed on a second plane different from the first plane, the third end of the second conductor being electrically connected to the first end of the first conductor, and the fourth end of the second conductor being positioned near the second end of the first conductor;
a third conductor having a fifth end and a sixth end and being disposed on the first plane, the fifth end of the third conductor being electrically connected to the fourth end of the second conductor, and the sixth end of the third conductor being positioned near the third end of the second conductor; and
a segment portion implemented as a slit and configured to divide at least one of the first conductor, the second conductor, or the third conductor into a first sub-conductor and a second sub-conductor,
wherein the segment portion has a capacitance value, and the at least one of the first conductor, the second conductor, or the third conductor and the segment portion are used as a resonator,
wherein a current flows from the first end of the first conductor to the second end of the first conductor in a first direction including a clockwise direction or a counterclockwise direction, and
wherein another current flows from the sixth end of the third conductor to the fifth end of the third conductor in a second direction opposite to the first direction.
