Embodiment 1

[0040] Please refer to figure 1 and figure 2 , Embodiment 1 of the present invention is: an ultra-wideband 5G MIMO antenna structure, which is mainly used for 5G communication of mobile terminals such as mobile phones, and will coexist with 4G LTE communication systems (and other antennas such as GPS, etc.). The existing 4GLTE antenna It has been placed on the two short sides of the phone, so the best place for the 5G MIMO antenna system to be placed in the phone will be the two long sides of the phone.

[0041] The ultra-wideband 5G MIMO antenna structure mainly includes a PCB board 1 and more than one antenna assembly 2, and more than one antenna assembly 2 is arranged on the PCB board 1 at intervals. Preferably, the number of the antenna components 2 is an even number of more than four, and the even number of antenna components 2 of more than four are symmetrically distributed on opposite sides of the PCB 1 . In this embodiment, the size of the PCB board 1 is 150mm x 75m...

Embodiment 2

[0054] Please refer to Figure 10 The difference between this embodiment and Embodiment 1 is that: the feed unit 21 is L-shaped, the top of the vertical branch 212 is connected to the end of the horizontal branch 211, and the horizontal branch 211 and the The second vertical radiator 223 is located on the same side of the vertical branch 212 . Specific as Figure 10 As shown, when the second vertical radiator 223 is connected to the right end of the horizontal radiator 221, the second vertical radiator 223 is located on the right side of the vertical branch 212, and the horizontal branch 211 is connected to the vertical Right side of the top of straight branch 212 . The feeding unit 21 can also generate high-frequency resonance.

Embodiment 3

[0056] Please refer to Figure 11 The difference between this embodiment and Embodiment 1 is that: the feed unit 21 is L-shaped, the top of the vertical branch 212 is connected to the end of the horizontal branch 211, and the horizontal branch 211 and the The second vertical radiators 223 are respectively located on opposite sides of the vertical branch 212 . Specific as Figure 11 As shown, when the second vertical radiator 223 is connected to the right end of the horizontal radiator 221, the second vertical radiator 223 is located on the right side of the vertical branch 212, and the horizontal branch 211 is connected to the vertical The top of the straight branch 212 is to the left. The feeding unit 21 can also generate high-frequency resonance.

[0057] In summary, the ultra-wideband 5G MIMO antenna structure provided by the present invention can be applied to 5G communication of mobile terminals, and can effectively cover all frequency bands under 6 GHz in 5G mobile co...

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to an ultra-wideband 5G MIMO antenna structure. Background technique [0002] With the rapid development of wireless communication technology, the fifth generation (5G) wireless communication system will be used on a large scale. In the next few years, new mobile terminal antennas and base station antennas will have a very broad market. In the fourth generation mobile communication (4G) system, 2x2 multiple-input multiple-output (MIMO) antennas have been widely studied and used in handheld mobile devices. According to the current research of various countries, the peak rate of 5G technology will increase by dozens of times compared with the current 4G technology. Therefore, the 2x2 or 4x4 MIMO antenna structure can no longer meet the requirements of transmission rate and connection reliability in 5G systems. In 5G systems, MIMO antenna structures with more antennas, ...
