Description

technical field [0001] The invention belongs to the technical field of wireless communication, and in particular relates to a decoupling device and a MIMO antenna. Background technique [0002] With the rapid development of smart mobile terminals, wireless data traffic is increasing exponentially, and the introduction and rapid development of the Internet of Things put forward higher requirements for future wireless communication systems. [0003] In the traditional 2D-MIMO technology, the antenna generally adopts a one-dimensional linear array antenna. The small number of ports leads to a wider wave width, and the interference between base stations is more serious, and the beam direction can only be mechanically adjusted in the horizontal dimension, and the energy in the vertical dimension cannot be transferred. Centralized to the user terminal, the communication efficiency is low. Compared with the traditional 2D-MIMO technology, in the 3D-MIMO technology, the antenna ado...
