Multi-frequency fusion base station antenna and communication equipment

Abstract

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; in the two second antennas with relatively high frequency bands, the two beams of working current with the same polarization direction excite the two beams of induced current on the same second part to counteract, and it is ensured that radiation energy of the induced current cannot cause interference to electromagnetic wave energy of the second antennas.

Description

technical field [0001] The embodiments of the present application relate to the technical field of communication equipment, and in particular to a multi-frequency fusion base station antenna and communication equipment. Background technique [0002] In engineering systems such as radio communication, radio and television, radar, and aviation and navigation, radio waves are required to transmit information to complete the work of the entire system. Antennas are the basic devices used to transmit or receive radio waves in these systems. [0003] With the development of 5G communication, antennas in communication equipment need to cover more and more frequency bands. For example, most base station antennas integrate different frequency bands in 3G, 4G, and 5G to ensure that a base station can send and receive wireless signals in different frequency bands. . In order to ensure the miniaturization and light weight of base station antennas, multi-frequency fusion base station ant...

Problems solved by technology

[0004] However, in the multi-frequency fusion base station antenna, the energy radiated by the high-frequency antenna is very easy to excite the induced current on the low-frequency antenna. The induced current radiates twice and is superimposed with the energy radiated by the high-frequency antenna. The electromagnetic wave signal of the high-frequency antenna causes strong interference
