High-gain 5G planar broadband four-way MIMO antenna

Abstract

The invention relates to a high-gain 5G planar broadband four-way MIMO antenna which comprises a lower support, an upper support and a connecting plate. The lower support is located on the lower side of the upper support, and the lower support and the upper support are connected through the connecting plate. A first reinforcing plate is arranged between the lower support and the upper support, and the first reinforcing plate is connected with the lower support and the upper support in a welding manner; the first hinged support is arranged on the upper portion of the upper support, and the first hinged support is fixedly connected with the upper support through a bolt. The electric push rod is arranged in the middle of the first hinged support and hinged to the first hinged support through a rotating shaft. The connecting cylinder is arranged at the side part of the electric push rod, and the connecting cylinder is connected with the electric push rod in an inserting manner; an AAU is arranged on one side of the connecting cylinder. Through improvement of an existing antenna, the MIMO antenna has the advantages of being convenient in AAU angle adjustment, high in strength of a supporting part, stable and safe in installation, high in gain and good in frequency characteristic, and therefore the problems and defects proposed in the background technology are effectively solved.

Description

technical field [0001] The invention relates to a high-gain 5G planar broadband four-way MIMO antenna, in particular to a high-gain 5G planar broadband four-way MIMO antenna. Background technique [0002] A MIMO antenna stands for Multiple Input Multiple Output. Typically used for ieee 802.11n, but can also be used for other 802.11 technologies. MIMO technologies can be broadly classified into two categories: transmit / receive diversity and spatial multiplexing. A MIMO antenna is sometimes called spatially diverse because it uses multiple spatial channels to transmit and receive data, and the capacity of the channel can be increased with MIMO technology. [0003] The angle of the existing AAU antenna can only be adjusted manually after installation, which is very inconvenient in high base stations. At the same time, the upper bracket and the lower bracket of the existing antenna bracket are of split design, and the overall strength is relatively weak. , cannot meet the inst...

Problems solved by technology

[0003] The angle of the existing AAU antenna can only be adjusted manually after installation, which is very inconvenient in a taller base station. At the same time, the upper bracket and the lower bracket of the existing antenna bracket are of split design, and the overall strength is relatively weak. , cannot meet the installation requirements of heavier AAUs. At the same time, traditional MIMO antennas have the disadvantages of low gain and poor frequency characteristics
