Description

technical field [0001] This patent application relates to the field of communication technologies, and in particular to an antenna unit, a Multiple-Input Multiple-Output (MIMO, Multiple-Input Multiple-Output) antenna and a terminal. Background technique [0002] At present, the traditional single input single output (SISO, single input single output) antenna system is not enough to meet the large capacity, high speed and high reliability requirements of the new generation wireless communication system due to the limitation of Shannon capacity. The objective fact is that how to achieve higher spectrum utilization has become an urgent problem to be solved in the development of new technologies in the field of wireless communication; multiple-input multiple-output (MIMO, Multiple-Input Multiple-Output) antenna system can effectively The communication link is decomposed into many parallel sub-channels, which can greatly increase the channel capacity, break through the limitation...

Problems solved by technology

[0003] However, when a multiple-input multiple-output (MIMO, Multiple-Input Multiple-Output) antenna system is applied to a base station, due to the large available space of the base station, the application of multi-antenna technology is easy to implement. For increasingly miniaturized terminal equipment , multiple antennas need to be concentrated in a small space. In order to obtain good performance, these antenna elements need to have good isolation, and at the same time, there must be a low correlation coefficient between the antenna elements; moreover, there are currently multiple Standards to meet different applications, the frequency bands covered by these standards are different, so the antenna system is required to be able to achieve multi-band work; in handheld devices (such as mobile phones), the space is very small, the antenna elements that make up the MIMO antenna The distances are small, and it is very difficult to design a MIMO antenna system that meets these requirements and performs well
