Problems solved by technology

[0003] However, with the development of 5G technology, more and more MIMO sub-antenna units need to be integrated into the limited space of the mobile terminal. Strong surface wave and space inductive coupling between antennas will deteriorate the performance of MIMO antenna arrays such as frequency band and efficiency

Abstract

The invention discloses a 5G mobile terminal MIMO (Multiple Input Multiple Output) antenna based on a chip integrated module unit, which is suitable for the field of mobile communication. The antenna comprises a dielectric substrate, a system metal floor and four integrated chip modules. The four integrated chip modules have the same physical size, are arranged at four corners of the system metal floor and are symmetrically distributed; each integrated chip module comprises two sub antenna units working at 3.5 GHz and two corresponding feed ports; and each sub-antenna unit is composed of a radiation slot and a feed microstrip line. In addition, a microstrip line branch structure is additionally arranged between the two sub-antenna units, and an additional anti-phase coupling path is introduced between the sub-antenna units, so that the aim of improving the isolation between the sub-antenna units is achieved. The 5G mobile terminal MIMO antenna uses the integrally designed chip integrated modules, is convenient to disassemble and exchange, and has the advantages of saving space and being low in cost, thereby having a good application prospect in 5G mobile phone terminals.

Description

Technical field: [0001] The invention belongs to the technical field of mobile communication, relates to the design of a mobile phone antenna, and in particular to a 5G mobile terminal MIMO antenna based on a chip integrated module. Background technique: [0002] In recent years, advances in antenna technology have been keeping pace with the development of mobile phones. With the increase of users' demand for mobile communication, 5G technology was born. 5G technology has many advantages, such as high communication capacity, high communication rate, and low latency. To meet the goals of 5G, MIMO technology, which can effectively expand channel capacity, has been developed. At the 2015 World Radio Conference, it was confirmed that 3.5GHz is one of the Sub-6GHz frequency bands, and this frequency band is also a current research hotspot. [0003] However, with the development of 5G technology, more and more MIMO sub-antenna units need to be integrated into the limited space ...
