Problems solved by technology

In order for a MIMO system to have good performance, the antenna elements must be uncorrelated (lower coupling), however, the space that can be reserved for antennas in mobile devices is very limited, making the spatial distance between antennas impossible Greater than or equal to a wavelength

Embodiment 1

[0019] refer to figure 1 , a high-isolation MIMO antenna that can be used as an antenna for smart mobile terminals such as mobile phones. The MIMO antenna includes a dielectric substrate 1, at least two antenna radiation ends 2, a filter decoupling network 3 and a ground plane (not shown in the figure), and each of the antenna radiation ends 2 and the filter decoupling network 3 is arranged on the dielectric substrate 1 One side can be arranged on the front side of the dielectric substrate 1 ; Multiple antenna radiation ends 2 form a MIMO antenna, and the filter decoupling network 3 is connected between the antenna radiation ends 2. By filtering the radio waves between the antennas, the radio waves radiated by one antenna are reduced from being absorbed by other antennas, thereby reducing the power of each antenna. The mutual coupling between the radiating ends 2 improves the isolation of the radiating ends of each antenna. The filter decoupling network 3 can adopt existing ...
