| description | Embodiments of this application relate to the field of mobile communications technologies, and provide a feed system, an array antenna, and a base station, to provide a phase-shift feed system having a simple structure. The feed system is located on a back surface of a metal plate. The feed system includes a plurality of first feed chambers and a plurality of first feed striplines suspended in the plurality of first feed chambers. Each of the plurality of first feed striplines includes a plurality of output ports. The plurality of first feed chambers and a ground plane of the metal plate share a metal surface. The metal surface has a plurality of openings corresponding to a plurality of first radiating elements located on a front surface of the metal plate. The plurality of output ports of each first feed stripline are connected, in a one-to-one manner, to the plurality of first radiating elements through the plurality of openings. The plurality of first feed striplines are used to provide transmission signals for the plurality of first radiating elements. |
