Problems solved by technology

In actual work, the antenna often needs to cover multiple frequency bands. However, as the structure of the terminal becomes more and more complex, the space left for the antenna becomes smaller and smaller, and it is difficult to install more antennas within a limited size. Difficult to cover more frequency bands

Abstract

The invention relates to an MIMO antenna and a terminal, and the MIMO antenna comprises a substrate which is provided with a first surface; the metal floor, the plurality of first sub-antennas, the second sub-antenna and the plurality of third sub-antennas are all laid on the first surface, the metal floor is multiplexed as a fourth radiator, and each sub-antenna is coupled with a feed slot of the metal floor through a feeder line of the sub-antenna. The sub-antennas can respectively cover intermediate frequency, high frequency and WIFI frequency bands, and participate in low-frequency radiation through the floor, so that the low frequency of each sub-antenna is expanded, and the low-frequency coverage of the MIMO antenna is realized. The scheme can be used as an integrated remote external antenna to be applied to 5G terminal equipment, and has high application value and wide application prospect.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, and in particular, to a MIMO antenna and a terminal. Background technique [0002] With the continuous development of 5G communication technology, MIMO antennas (Multiple Input Multiple Output Antennas) have been extensively studied, and the deep integration of this technology with industrial terminals has become one of the hotspots in current mobile communication research. In practice, the antenna often needs to cover multiple frequency bands. However, as the structure of the terminal becomes more and more complex, the space left for the antenna becomes smaller and smaller, and it is difficult to set up more antennas in a limited size. It is difficult to cover more frequency bands. [0003] Based on this, a new MIMO antenna and terminal are urgently needed. SUMMARY OF THE INVENTION [0004] Embodiments of the present application provide a MIMO antenna and a terminal, w...
