Single-sided feeder line ultra-wideband MIMO (Multiple Input Multiple Output) antenna

Abstract

The invention provides a single-sided feeder line ultra-wideband MIMO antenna, and the antenna comprises a terminal metal housing which is internally provided with a rectangular accommodation groove; a plastic bracket which is positioned in the rectangular accommodating groove and is connected with the terminal metal shell through a screw; a PCB substrate which is connected with the plastic bracket through double faced adhesive tape, wherein a first antenna unit, a second antenna unit and a third antenna unit are arranged on the face, away from the plastic bracket, of the PCB substrate, and a fourth antenna unit, a fifth antenna unit and a sixth antenna unit are arranged on the face, close to the plastic bracket, of the PCB substrate. The first antenna unit and the sixth antenna unit are arranged in a crossed manner, the second antenna unit and the fifth antenna unit are arranged in a crossed manner, and the third antenna unit and the fourth antenna unit are arranged in a crossed manner. The antenna not only covers an existing common 4G network, but also covers an existing 5G mainstream network (sub-6G); the size is small, assembling is simple, cost is low, and batch production is easy.

Description

technical field [0001] The invention relates to the technical field of antennas, in particular to a single-sided feeder ultra-wideband MIMO antenna. Background technique [0002] With the rapid development of 5G communication technology, wireless communication terminal equipment needs to support more and more frequency bands, and the number of antennas is also increasing. MIMO (Multiple-Input Multiple-Output, [0003] Multiple-input multiple-output system) technology has become the mainstream technology of 5G mobile communication equipment. The current mobile communication terminals tend to be miniaturized and planarized, so the antenna design must be as small as possible while maintaining performance. [0004] For some current large-scale enterprise routing devices that include 5G frequency bands, the commonly used operating frequency bands are LTE (1710-2690MHz), NR (3300-5000MHz), and WIFI (2400-2500MHz, 5150-5850MHz), and a multi-antenna solution is required. For this ...

AI Technical Summary

Problems solved by technology

When the external antenna is used, the number of antennas is too large, it takes up a lot of space, the layout is difficult and affects the overall appearance

If the built-in antenna is used, the antenna must be embedded inside the communication device, then the internal environment of the communication device will seriously interfere with the antenna pattern

In addition, when the number of antennas is large, multiple antennas must be arranged in a small internal space, and there is a big problem with the isolation
