Abstract: An antenna array is provided, which may include a connection portion and a plurality of antenna units. The antenna units may be disposed on the two sides of the connection portion respectively. The proximal end of each of the antenna units may be connected to the connection portion and the distal end of one or more of the antenna units may be grounded. The length of each of the antenna units may be less than or equal to ¼ wavelength of the operating frequency of the antenna array, and the distance between any two adjacent antenna units may be less than or equal to ½ wavelength of the operating frequency of the antenna array.
