Abstract

The invention discloses a high isolation MIMO antenna for 5G mobile terminals, comprising a rectangular base plate and a metal base plate, a three-unit antenna module is arranged on the base plate, and the three-unit antenna module includes a first dipole antenna whose radiating surface is perpendicular to the base plate unit, the second dipole antenna unit and the monopole antenna unit; the two right-angled sides of one top corner of the substrate are respectively located on the radiation surfaces of the first dipole antenna unit and the second dipole antenna unit, and the monopole The radiation surface of the antenna unit is parallel to the radiation surface of the first dipole antenna unit or the second dipole antenna unit, and is perpendicular to the radiation surface of the other dipole antenna unit. It has the advantages of high isolation, effectively reducing mutual coupling between antennas in a compact space, improving space utilization, compact structure, reducing the volume of the antenna, and being able to cover the frequency band required for 5G communication.

Description

technical field [0001] The present invention relates to antenna technology, in particular to a compact high-isolation MIMO antenna for 5G mobile terminals. Background technique [0002] In recent years, with the rapid development of wireless communication and the continuous improvement of communication system capacity, the electromagnetic wave propagation environment has become more and more complex, and the improvement of people's quality of life has also put forward higher requirements for wireless mobile communication systems and mobile phones. Different from the traditional communication system, in the MIMO system including spatial diversity and spatial multiplexing, the multipath effect has become a favorable condition. reliability. [0003] The fifth generation (5G) mobile communication system will be deployed on a large scale in 2020. Compared with the current 4G system, the 5G mobile communication system has many advantages such as higher transmission rate and short...

Problems solved by technology

Decoupling can improve space utilization and ensure the normal operation of MIMO antennas. It is a traditional decoupling method for antennas with compact structures. The traditional decoupling method is to introduce an external decoupling structure into the antenna, which takes up a lot of space and the space utilization rate is not high. The coupling structure will also bring channel coupling and change the original characteristics of the antenna, which can no longer meet the needs of 5G mobile terminals.
