Antenna unit for a wireless charging and wireless charging module having the same

摘要

A wirelessly-charged antenna unit and a wireless power-charging module including the same are provided. A wirelessly-charged antenna unit according to an embodiment of the present invention includes a circuit board; And a second antenna pattern formed on one surface of the circuit board for wireless charging, wherein the single conductor is in the form of a plurality of windings, and the single conductor has a line width different from one another according to the position. According to the present invention, since the line widths of the individual windings constituting the antenna pattern are different from each other, the resistance value of the antenna is reduced. Therefore, it is possible to minimize the amount of heat generated during wireless charging while satisfying the specifications of the antenna, Since the clearance is formed on the inner side of the antenna, it is easy to adjust the inductance, the outer diameter, the inner diameter, and the arrangement of the antenna, thereby improving the freedom of designing the antenna.
