Antenna structure and electronic equipment

Abstract

The invention discloses an antenna structure and electronic equipment with the antenna structure. The antenna structure includes a first antenna, a second antenna, and a three-dimensional decoupling structure located on at least two planes, the three-dimensional decoupling structure includes a conductor, and at least part of the three-dimensional decoupling structure is located on the first antenna and the space between the second antenna. Compared with the prior art, the antenna structure disclosed in the present invention and the electronic equipment with the antenna structure can effectively achieve the antenna decoupling effect through the three-dimensional decoupling structure, so that the degree of degradation of the antenna performance due to coupling can be reduced, and at the same time The three-dimensional space of the system can be better utilized, and the horizontal area occupied by the system can be reduced to improve the utilization rate of the limited space, and there is no need to carry out metal clearance or avoidance on the circuit board, so as to maintain the integrity of the circuit board; Therefore, comprehensively speaking, the overall competitiveness of the product can be significantly improved.

[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
