Abstract

The invention discloses a self-decoupling high-isolation MIMO mobile phone antenna which comprises a substrate, an antenna unit, a feed unit, a coaxial feed line and a floor. The base plate is composed of a bottom face horizontal base plate and two side face vertical base plates. The antenna unit is composed of an inverted-T-shaped metal patch and located on the outer side of the side face substrate. The inverted-T-shaped metal patch is formed by sequentially and symmetrically connecting a first rectangle, a second rectangle, a third rectangle and a fourth rectangle. The feed unit is composed of a T-shaped metal patch of a side substrate and a rectangular metal patch of a bottom horizontal substrate, the T-shaped metal patch is located on the inner side of the side substrate, and the T-shaped metal patch is formed by connecting a fifth rectangle and a sixth rectangle; the floor is printed on the back of the bottom horizontal substrate; according to the antenna provided by the invention, the structures of the antenna units are changed, so that the antenna units can realize self-decoupling, the isolation between the antenna units is greatly improved, the frequency band of 5G 3.3 GHz to 3.6 GHz is covered, and the problems of complex decoupling mode and low isolation in the prior art are solved.

Description

technical field [0001] The invention relates to the technical field of antennas, in particular to a self-decoupling high-isolation MIMO mobile phone antenna. Background technique [0002] With the increasing demand for channel capacity and spectrum utilization efficiency of mobile communication systems, higher requirements are placed on the antenna performance of 5G mobile terminals, so the research on this type of antenna is highly regarded. At present, the 2×2 MIMO antenna system for 4G LTE (Long Term Evolution) wireless communication has been widely used in mobile terminals. However, for 5G wireless communication, the 2×2 MIMO system cannot meet its data transmission rate. Compared with the 4G MIMO antenna system, the 5G MIMO mobile terminal needs to integrate at least 6 antenna elements. [0003] When the number of antennas working in the same frequency band increases, the problem of isolation between antenna units and the miniaturization of each antenna unit will foll...
