Massive MIMO electrical adjusting antenna

Abstract

A Massive MIMO electrical adjusting antenna comprises a physical phase shift portion and a digital phase shift portion. The physical phase shift portion comprises a radiation unit module, a power division network module, a phase shifter module, a connection structure module, a driving device and an RET control portion which are successively connected from top to bottom. The radiation unit module comprises a plurality of groups of radiation units arranged in parallel. The power division network module comprises a plurality of groups of power division networks arranged in parallel. The phase shift module comprises a plurality of phase shifters arranged in parallel, and the connecting structure module comprises a plurality of connecting structures arranged in parallel. The plurality of radiation units in a single group are connected in parallel and are correspondingly connected with a group of power division networks. The single-group power dividing network is connected to one phase shifter, the phase shifter is correspondingly connected with the connecting structure respectively, the connecting structures are connected to the driving device together, the driving device is electrically connected with the RET control portion, and the connecting structures are connected with the driving device and the phase shifters respectively and drive the phase shifters to move. In the invention, the number of ports of the antenna is prevented from being increased, and a beam scanning function can be covered more widely.

Description

technical field [0001] The present invention relates to the technical field of 5G antennas, in particular to a Massive MIMO electrically adjustable antenna. Background technique [0002] At present, Massive MIMO antennas are an important part of 5G mobile communication network deployment. The use of large-scale array antennas can achieve more accurate beamforming and space division multiplexing, improving network capacity and spectrum efficiency. The Massive MIMO antenna system can perform beam scanning in both horizontal and vertical directions and can adjust its beam direction to enhance area coverage. Currently, Massive MIMO antennas mainly include three forms: 16TR, 32TR, and 64TR. The volume, power consumption, and cost of Massive MIMO antennas Also incremented by increasing the number of ports. [0003] The traditional Massive MIMO antenna mainly realizes its beam scanning function through the digital phase shifting of the main device in the background (such as Figur...

Problems solved by technology

[0003] The traditional Massive MIMO antenna mainly realizes its beam scanning function through the digital phase shifting of the main device in the background (such as Figure 10 ), and to achieve wider coverage, this scanning method cannot avoid increasing the number of ports of the antenna, and it is also inevitable to increase the cost of the antenna. How to effectively control the cost of the antenna has become the primary problem
