COIL STRUCTURE

A coil structure applied in the field of wireless charging comprises a circuit board and a conductor. The conductor is arranged on the circuit board. The conductor comprises a plurality of coil turns, an input terminal, an output terminal, and a plurality of first capacitor structures. The coil turns are formed around a center point. The input terminal is connected to a one terminal of the coil turns. The outlet terminal is connected to another terminal of the coil turns. Each of the first capacitor structures is arranged on a corresponding one of the coil turns. Distance between the first capacitor structures and the output terminal is smaller than a distance between the first capacitor structures and the input terminal, and the first capacitor structures do not overlap with the output terminal.
