Small-scale LTE multi-array antenna

Abstract

The invention provides a small-scale LTE multi-array antenna. In the small-scale LTE multi-array antenna, each radiation unit comprises a dual-polarized oscillator and baluns, the dual-polarized oscillator comprises two separate dipoles, each feeding network employs a planar structure, feeding points between network ports are located in the same horizontal line, and the radiation units are placed by employing a strong coupling mode. According to the antenna, the strong-coupling radiation unit technology is employed, the spacing between the radiation units is shortened, and the length of the whole antenna is shorter; the low-profile radiation units are employed so that the height of the antenna is reduced, the overall size of the antenna is only 50% of the size of the same kind of product through comprehensive effect, the occupation of the antenna space is greatly reduced, and the gain of unit arrays is high; and the feeding networks with the integrated planar structures are employed so that the amplitude and the phase precision are high. According to the antenna, excellent performance of mobile communication can be guaranteed.

Description

technical field [0001] The invention relates to the technical field of mobile communication base station antenna equipment, in particular to a miniaturized LTE multi-array antenna. Background technique [0002] With the continuous development of my country's mobile communication industry, especially the commercialization of 4G, the density of base stations of major operators is increasing, and the number of base station antennas on the same tower is also increasing, which leads to more and more sky space resources of towers. getting nervous. Compared with the existing ordinary products, the miniaturized base station antenna can save the current precious space resource conditions. At the same time, in order to reduce the worries of ordinary people about electromagnetic wave signal radiation, operators also hope that the size of the base station antenna should be as small as possible. While shrinking, the weight of the antenna will generally be reduced, making it easier to ins...

AI Technical Summary

Problems solved by technology

[0004] At present, in order to shorten the size of the antenna, most of the miniaturized base station antennas in the industry adopt the scheme of reducing the number of radiating elements and shortening the overall length of the antenna. The gain index of the antenna is reduced, and the reduction of the antenna gain will lead to the reduction of the coverage area of ​​the antenna, which will affect the coverage effect of the network and the quality of the call.
