The invention relates to an ultra-wide frequency band multi-band array antenna which comprises a metal reflection plate, a low-frequency radiation unit and a high-frequency radiation unit. The low-frequency radiation unit and the high-frequency radiation unit are mounted on the metal reflection plate, the low-frequency radiation unit works on a low-frequency band, and the high-frequency radiation unit works on a high-frequency band. The low-frequency radiation unit comprises two low-frequency oscillators which are both in +/-45-degree polarization and are mounted in a mutually orthogonal mode, the two low-frequency oscillators are connected with a feed network, and a +/-45-degree polarization far field radiation directional diagram is generated; the high-frequency radiation unit comprises two high-frequency oscillators which are both in +/-45-degree polarization and are mounted in a mutually orthogonal mode. The multi-band array antenna is capable of covering a 694-960 MHz ultra-wide frequency band and a 1710-2690 MHz ultra-wide frequency band and is simple in structure so as to be compatible with all frequency bands of a current mobile communication network.
