Problems solved by technology

However, the layout of multiple antennas in the same frequency band is too dense, and isolation is a big problem
The conventional way to increase the isolation is to use orthogonal antenna polarization or increase the distance between the antennas, and it is extremely difficult to realize these two points in the mobile terminal 8*8 MIMO antenna system

Abstract

The invention provides a MIMO antenna system of a terminal. The system is composed of eight antennas that are divided into two groups, three groups or four groups of compact high-isolation antenna units; each compact high-isolation antenna unit group includes two antennas. When two groups of compact high-isolation antenna units are arranged, the two groups of compact high-isolation antenna units are arranged at the edge of a main board of the terminal at an interval; and the rest of four independent antennas are arranged at intervals by being far away from the main board in the terminal or inan antenna synchronization multiplexing manner based on the fixedly setting function inside the terminal. According to the MIMO antenna system, the space is saved.

Description

technical field [0001] The present invention relates to the technical field of mobile terminal equipment antennas, in particular to a terminal MIMO (Multiple-Input Multiple-Output, Multiple-Input Multiple-Output) antenna system. Background technique [0002] With the coming of the fifth-generation mobile communication method, MIMO technology becomes more and more important, and in the MIMO system, the design and layout of multiple antennas are crucial. After nearly five generations of mobile communication development, the requirements for antenna frequency bands have become wider and wider, and the number of antennas has also increased, which means that in a mobile terminal, the space required for antennas is also increasing. This contradicts the current more compact ID design. It is an inevitable requirement for the development of a new generation of mobile communication terminals to be able to design as many groups of antennas as possible in a limited space while ensuring...
