Abstract

The invention belongs to the technical field of communication equipment, and particularly relates to a 3D-MIMO dimension adjustable antenna, which comprises an antenna base, wherein a signal receivingseat is fixedly installed at one end of the antenna base, and is of a triangular structure, and a signal receiving mechanism is arranged on the surface of the signal receiving seat. According to theantenna with the adjustable 3D-MIMO dimension, a plurality of first hydraulic rods are controlled by electromagnetic valves to extend outwards or contract inwards, and modules are gradually expanded outwards or inwards from the middle to form an outward or inward arc shape, so that the signal receiving range is wide due to outward expansion, the signal reception is centralized through inward expansion, and the signal reception is good; and the electromagnetic valves control second hydraulic rods to extend upwards, the multiple antenna modules extend upwards one by one to form an outward trapezoid shape to adjust the signal receiving dimension space, and one electromagnetic valve in a electromagnetic valve set is in one-to-one correspondence with one hydraulic rod in a hydraulic rod set soas to replace and change any elastic module.

Description

technical field [0001] The invention relates to the technical field of communication equipment, in particular to a 3D-MIMO dimensionally adjustable antenna. Background technique [0002] MIMO technology refers to the ability to double the capacity and spectrum utilization of the communication system without increasing the bandwidth. It can be defined as the existence of multiple independent channels between the transmitting end and the receiving end, that is to say, between the antenna units There is sufficient separation, therefore, the correlation of the signals between the antennas is eliminated, the link performance of the signals is improved, and the data throughput is increased. [0003] On the one hand, 3D-MIMO can flexibly adjust the beam direction in the horizontal and vertical dimensions to form narrower and more precise directional beams, thereby greatly improving the energy received by terminals and enhancing cell coverage; on the other hand, 3D-MIMO can fully U...
