Multi-frequency fusion base station antenna and communication equipment

The embodiment of the invention provides a multi-frequency fusion base station antenna and communication equipment. The multi-frequency fusion base station antenna comprises a grounding plate and at least one antenna unit, the antenna unit comprises a first antenna and a plurality of second antennas arranged in an array, the frequency band of the first antenna is lower than that of the second antennas, and the first antenna is located above the side, away from the grounding plate, of the plane where the second antennas are located; the first antenna comprises a first additional antenna, the first additional antenna comprises four first parts and a second part, the four first parts are sequentially arranged in the circumferential direction, the second part is connected between every two adjacent first parts, and a height difference exists between a main body part of each second part and the corresponding first part relative to the grounding plate, so that the second parts are of a three-dimensional structure;
