Abstract: An antenna module and a wireless communication device using the same are provided. The antenna module is used for receiving or transmitting at least a wireless signal. The antenna module includes three independent antennas each having a bottom end and a center line. The bottom ends are substantially disposed on the same plane. The bottom ends are substantially arranged in the shape of a regular triangle. Each distance between two neighboring bottom ends is larger than a quarter of the wavelength of the wireless signal. The included angle between each of the center lines and the plane substantially ranges from 50° to 80°.
