  • Patent number: 11114764
    Abstract: Disclosed is an antenna module that combines a vertical winding type antenna and a horizontal winding type antenna, thus minimizing a mounting space, manufacturing costs, and design considerations. That is, the antenna module combines the vertical winding type antenna and the horizontal winding type antenna to form an antenna for resonating in the first frequency band and the second frequency band, and an antenna for wireless power transmission, thus implementing antenna performance that is equal to or greater than that of the multi-band antenna composed of the horizontal winding type radiation pattern while minimizing a mounting space.
