A compact 5G MIMO antenna system includes at least two antenna assemblies. Each antenna assembly includes a first antenna unit and a second antenna unit, wherein the first antenna unit includes a first radiation assembly, a first feed branch and a ground branch; the second antenna unit includes a second radiation assembly, a second feed branch and the ground branch; the ground branch is located between the first radiation assembly and the second radiation assembly; the first feed branch is arranged close to an end, away from the ground branch, of the first radiation assembly; and the second feed branch is arranged close to an end, away from ground branch, of the second radiation assembly. The antenna system improves the isolation between the first antenna unit and the second antenna unit and compacts the overall structure of the antenna assembly, which has simple structure, high antenna efficiency, and convenient use.
