An antenna array module includes at least two antenna units mounted on a surface of a feed network circuit board with two power division circuits, and a filter mounted on a surface of the feed network circuit board with two coupling circuits. Each power division circuit includes an input end and a plurality of output ends. One power division circuit feeds an antenna unit for &#x2212;45&#xb0; polarization, and the other power division circuit feeds an antenna unit for +45&#xb0; polarization. Each coupling circuit includes a radio frequency input end and an output end, and the output end of the coupling circuit is electrically connected to the input end of the power division circuit. The filter includes at least two output ends that are electrically connected to the radio frequency input end of the coupling circuit. A base station antenna includes a mounting structure and a connection structure.
