The antenna includes a bottom plate, first reflecting plates are arranged on the two sides of the bottom plate. The bottom plate is provided with a low-frequency radiation antenna array, a first high-frequency radiation antenna array, a second high-frequencyradiation antenna array and a third high-frequency radiation antenna array. The low-frequency radiation antenna array comprises a plurality of low-frequency oscillators. The first high-frequency radiation antenna array comprises a plurality of first high-frequency oscillators, the second high-frequency radiation antenna array comprises a plurality of second high-frequency oscillators, the third high-frequency radiation antenna array comprises a plurality of third high-frequency oscillators, the low-frequency oscillators and the first high-frequency oscillators are arrayed into a straight lineand distributed in the center of the bottom plate at equal intervals, and part of the first high-frequency oscillators are embedded into the low-frequency oscillators. The second high-frequency oscillators and the third high-frequency oscillators are arrayed into a straight line and distributed on the bottom plate at equal intervals, and the second high-frequency radiation antenna array and the third high-frequency radiation antenna array are evenly distributed on the two sides of the low-frequency radiation antenna array.

Description

technical field [0001] The invention belongs to the technical field of base station antennas, and in particular relates to a one-low, three-high, multi-port base station antenna. Background technique [0002] In recent years, with the increase of mobile communication network standards, in order to save site and antenna resources, reduce the difficulty of property coordination, and reduce investment costs, multi-frequency array antennas with co-site and co-location have become the first choice for network construction. Moreover, in existing wireless communication systems, MIMO (Multiple-Input Multiple-Output) antenna technology is an important key technology to improve the quality and efficiency of mobile communication. MIMO technology can make full use of space resources and realize Multi-transmission and multi-reception can greatly increase the system channel capacity, improve channel reliability, and reduce the bit error rate without increasing spectrum resources and anten...

Problems solved by technology

[0005] In order to solve the problem that the existing base station antenna cannot realize multi-port antenna supporting one low frequency band and three high frequency bands at the same time, and cannot meet the technical requirements that both high and low frequencies are broadband, and at the same time the radiation performance of the base station antenna is poor, the present invention discloses a One low and three high multi-port base station antennas, a low-frequency radiation antenna array, a high-frequency radiation antenna array 1, a high-frequency radiation antenna array 2 and a high-frequency radiation antenna array 3 are simultaneously arranged on the base plate with reflectors on both sides. The antenna can support one low frequency and three high frequencies at the same time. At the same time, the antenna has a good isolation index and radiation performance, and the performance has been greatly improved, effectively solving the above problems
