Abstract
Provided are a combo antenna unit, and a wireless power receiving module including the same. The combo antenna unit includes a wireless power transmission antenna and at least one additional antenna using a different frequency band from the wireless power transmission antenna. The wireless power transmission antenna includes a radiator formed of a loop-shape-wound flat coil. According to the present invention, it is possible to reduce resistance so as to decrease heat generation and increase charging efficiency, and minimize the amount of circuit board used, thereby reducing overall production costs.
