Abstract
(EN)
Disclosed in the embodiments of the present application are a MIMO antenna, comprising a reflective plate, a first antenna unit, a second antenna unit, and a first decoupling line. The first antenna unit comprises a first bracket arranged upright on the reflective plate and a first radiating arm positioned on the first bracket. The second antenna unit comprises a second bracket arranged upright on the reflective plate and a second radiating arm positioned on the second bracket. The direction of polarisation of the first radiating arm is the same as the direction of polarisation of the second radiating arm. The first decoupling line comprises a first coupling section, a first transmission section, a first connecting section, a second transmission section, and a second coupling section connected in sequence. The first connecting section is positioned on the reflective plate, the first coupling section is positioned on the first bracket and is coupled to the first radiating arm, and the second coupling section is positioned on the second bracket and is coupled to the second radiating arm. The present MIMO antenna has a high degree of isolation. Also disclosed in the embodiments of the present application is a base station.
