COMPACT 5G MIMO ANTENNA SYSTEM AND MOBILE TERMINAL

摘要

Disclosed is a compact 5G MIMO antenna system, comprising at least two antenna assemblies. Each antenna assembly comprises a first antenna unit and a second antenna unit; the first antenna unit comprises a first radiation assembly, a first feed branch, and a grounding branch; the second antenna unit comprises a second radiation assembly, a second feed branch, and the grounding branch; the grounding branch is located between the first radiation assembly and the second radiation assembly; the first feed branch is provided close to one end of the first radiation assembly distant from the grounding branch; the second feed branch is provided close to one end of the second radiation assembly distant from the grounding branch. The first antenna unit and the second antenna unit share one grounding branch for coupling grounding, so that the isolation degree between the first antenna unit and the second antenna unit is improved, and the overall structure of the antenna assembly is also more compact. The antenna system in the present invention is simple in structure, high in antenna efficiency and convenient to use.
