Abstract

The invention relates to a multi-band array antenna compact in structure. The multi-band array antenna compact in structure comprises a metal reflecting board, a low frequency radiation unit working in a low frequency band and a high frequency radiation unit working in a high frequency band. The low frequency radiation unit and the high frequency radiation unit are arranged on the metal reflecting board in a nested mode, and the orthographic projections of the low frequency radiation unit and the high frequency radiation unit are not overlapped. The low frequency radiation unit is formed by connecting a horizontal oscillator, a vertical oscillator and a feed network. A low frequency oscillator is flexible in structure, and parameters such as separation distances can be flexibly configured according to practical application requirements. By the adoption of the structure, the stability of radiation characteristics of multi-band frequency array antennas in an ultra wide band range can be kept, the multi-band array antenna compact in structure is compatible with all 2G, 3G and 4G LTE standards in mobile communication, the number of antennas used by a base station is reduced, station distribution cost is reduced, and operation maintenance cost can also be reduced.

Description

technical field

[0001] The invention relates to the communication field, in particular to a multi-band array antenna with compact structure. Background technique

[0002] In recent years, the large-scale use of smart mobile terminals represented by smart phones and tablet computers has led to rapid growth of data services in mobile communications. In order to meet the requirements for high-speed data transmission in mobile communications, major operators at home and abroad are vigorously developing the fourth-generation (4G) mobile communication technology mainly based on TD-LTE and FDD-LTE. Today, 2G, 3G and the upcoming 4G LTE network coexist, and multiple systems using different frequency bands exist at the same time, requiring the use of base station antennas that can work in different frequency bands. Using ordinary narrow-band antennas, a base station needs to arrange many sub-antennas, which increases system complexity and property costs. In order to reduce the cost...
