Abstract: An antenna array and a wireless communications device are disclosed. The antenna array includes at least two directional antennas in different directions. Each directional antenna includes an antenna element, a reflector, a feed line coupled to the antenna element, and a switch for controlling the feed line. The antenna element is a microstrip dipole antenna element. The reflector is a parasitic microstrip antenna element. A length of the reflector is greater than a length the antenna element. Two ends of the reflector are bent toward the antenna element. A distance between midpoints of reflectors of any two directional antennas is less than a distance between midpoints of antenna elements thereof. Because the reflectors of the antenna array are located on an inner side of a pattern enclosed by the antenna elements of directional antennas, a size of the antenna array is small.

Abstract: A printed dipole antenna includes a first printed dipole, a second printed dipole, a third printed dipole, a fourth printed dipole, a first feed line, a second feed line, a third feed line, and a fourth feed line. Feed lines parallel to the printed dipoles each include different segments, and each segment approaches a printed dipole on one side of the segment to suppress parasitic emission of the feed lines, and implement a low sidelobe level of the printed dipole antenna.
