Mobile communication terminal dual polarization sub-6GHz antenna system

Abstract

The present invention discloses a mobile communication terminal dual polarization sub-6GHz antenna system. The system comprises a PCB mainboard covering four corner angles of a mobile communication terminal, and a first antenna unit and a second antenna unit which are orthogonally arranged on the PCB mainboard in a corner area range, the PCB mainboard comprises an outer-layer surface, a metal floor layer, a bottom-layer surface, and a dielectric layer configured to separate the outer-layer surface, the metal floor layer and the bottom-layer surface from one other, the first antenna unit is arranged on the outer-layer surface, the second antenna unit is arranged on the bottom-layer surface, the first antenna unit and the second antenna unit are both monopole antennas, one end of the first antenna unit is provided with a first feeding point, and one end of the second antenna unit is provided with a second feeding point. The resonant frequency of the mobile communication terminal dual polarization sub-6GHz antenna system is 3.4-3.6GHz, can combine an MIMO array according to actual demands and can be used individually; and moreover, the mobile communication terminal dual polarization sub-6GHz antenna system employs a dual-polarization antenna implementation mode to ensure achieving of good radiation without mutual interference in a condition that the antenna is located in a small space distance.

Description

【Technical field】 [0001] The invention belongs to the technical field of communication, and in particular relates to a dual-polarization sub-6GHz antenna system for a mobile communication terminal. 【Background technique】 [0002] The fifth generation of mobile communication (5G for short) is currently being extensively researched all over the world. The fifth-generation mobile communication can be divided into two categories according to the frequency band requirements of communication: one is the sub-6GHz range, and the specific frequency bands that have been filed by the Ministry of Industry and Information Technology of China are 3.4-3.6GHz and 4.8-5.0GHz, and the basic demand indicators have been clearly defined The channel capacity of communication within this range reaches 10Gbps / s; another category is millimeter wave band communication (the so-called millimeter wave communication means that the actual wavelength of the electromagnetic wave for communication is on the ...
