Abstract: A wireless communications device is provided. A first antenna and a second antenna are disposed on the wireless communications device, where an electrical length of the first antenna is N times an electrical length of the second antenna, where N is an integer greater than or equal to 1. The first antenna and the second antenna are disposed on a printed circuit board by means of common ground connection, that is, ground points of the first antenna and the second antenna are a same ground point, which reduces input impedance at the ground point of the first antenna and the second antenna, so that energy fed from the antennas is evenly distributed in a horizontal direction and a vertical direction of the printed circuit board.
