Abstract

The invention relates to a three-frequency two-element MIMO antenna capable of being used for WLAN/WiMAX/5G. The three-frequency two-element MIMO antenna comprises a substrate, an antenna and floors,and is characterized in that the antenna comprises two radiation units; high-frequency branches are arranged on the radiation units; the floors and the radiation units are arranged correspondingly, and low-frequency branches are arranged on the two floors; the low-frequency branches are adjacent; the high-frequency branches are located on the sides, away from the low-frequency branches, of the radiation units; and the whole antenna is of a symmetrical structure. Compared with the prior art, the three-frequency two-element MIMO antenna has the advantages of better isolation, low loss, miniaturization and the like.

Description

technical field [0001] The present invention relates to a MIMO antenna, in particular to a triple-frequency binary MIMO antenna applicable to WLAN / WiMAX / 5G. Background technique [0002] With the development of the mobile Internet, more and more devices are connected to the mobile network, and new services and applications emerge one after another. The surge in mobile data traffic will bring severe challenges to the network. In order to meet the growing demand for mobile traffic, it is necessary to develop a new generation of 5G mobile communication network. Compared with other networks, 5G network has faster speed, larger capacity, and greatly shortens the delay in the transmission process, which makes the network connection more extensive and rapid, and the speed and quantity of data processing are significantly improved. interconnection among them. In November 2017, the Ministry of Industry and Information Technology announced that the frequency bands used for 5G mobile...
