description The present invention relates to the technical field of communication antennas and in particular to a multi-system base station antenna capable of controlling beam width. The multi-system base stationantenna capable of controlling beam width in the present invention comprises a metal reflector and radiating elements mounted on the metal reflector; the radiating elements are arranged parallel to each other along a plurality of columns of longitudinal lines and in a manner of equal number but unequal intervals, to form a multi-column antenna array; and each column of first radiating elements ofthe multi-column antenna array are located on the same transverse straight line and the array directions intersect perpendicularly. The multi-system base station antenna capable of controlling beam width in the invention can control the radiation characteristics of the antenna subsystem such as beam width, gain, beam deviation degree and cross polarization discrimination rate by adjusting the power ratio and phase differe
