Abstract

The invention belongs to the technical field of communication equipment, in particular to a 3D-MIMO dimension-adjustable antenna, comprising an antenna base, one end of the antenna base is fixedly mounted with a signal receiving seat, the signal receiving seat is a triangular structure, and the surface of the signal receiving seat is A signal receiving mechanism is provided. The 3D‑MIMO dimension-adjustable antenna controls the multiple first hydraulic rods to extend or contract inward through solenoid valves, and the modules gradually expand outward or inward from the middle to form an outward or inward arc. The outward expansion makes the signal reception range wider, and the inward expansion makes the signal reception more concentrated and better to receive the signal. The solenoid valve controls the second hydraulic rod to extend upward, and multiple antenna modules extend upward one by one, and multiple elastic modules are formed. In order to adjust the signal receiving dimension space for the outward trapezoidal shape, one solenoid valve in the solenoid valve group corresponds to one hydraulic rod in the hydraulic rod group, and any elastic module can be replaced and changed.

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...
