Problems solved by technology

[0002] In the 5G (fifth-generation mobile communication) era, due to the need to meet the communication requirements of MIMO (multi-input and multi-output, that is, multiple input and multiple output) with more channels, and to cover more new frequency bands, the number of antennas in the mobile phone Compared with the previous generation of mobile communication, the number of mobile communication generations has increased significantly, but the size of the mobile phone has not increased proportionally, so the distance between the antennas has been significantly shortened, and the coupling phenomenon between antennas of the same frequency or non-same frequency has become more serious (especially the same frequency or near-frequency antennas), the performance of the antenna is significantly reduced, and the user's wireless communication experience is degraded
However, the layout method cannot be used well in a space-constrained and compact system, so the effect is often not significant. The external structural method will often increase the distance between antennas, which will affect the system compactness and even the system size. The defective ground method will destroy the system. Therefore, in the actual compact system, the feasibility is often low, and the artificial material method design is more complicated, and often requires additional space or carrier, and the circuit method design is often more complicated, especially for multi-frequency or broadband decoupling, The eigenmode method often has poor decoupling effect on multi-band or wide-band, while the traditional neutralization line method is often a plane line connecting the antenna body, and the area under the neutralization line line often needs to be clear, so it occupies more board area. And it has higher environmental requirements for the board end and even the system
