Problems solved by technology

[0003] In the 5G era, in order to achieve high-speed data transmission, at least four antennas that can cover the 5G frequency band are required. However, limited by the size of wearable devices, more antennas will lead to deterioration of the isolation between antennas. At the same time, it is difficult to meet Dual frequency use requirements

Abstract

The invention discloses a 5G double-frequency MIMO antenna structure and an intelligent wearable device. The antenna structure comprises a mainboard and antenna supports arranged in parallel at two opposite ends of the mainboard; each antenna support is provided with two antennas to form an antenna assembly; the antenna assemblies on the two antenna supports are symmetrically arranged relative to the mainboard; the two antennas on the same antenna support are symmetrically arranged; each antenna is provided with a feed point, and the feed points of the two antennas on the same antenna support are arranged at the ends, away from each other, of the two antennas. The antenna assemblies are symmetrically arranged, and the feed points of the two antennas on the same antenna support are arranged at the ends, far away from each other, of the two antennas, so that the requirement for high isolation of the antennas can be met to the maximum extent, the structure is simple, and a four-antenna structure covering the 5G frequency band of China Mobile (4.8-4.9 GHz), China Unicom (3.5-3.6 GHz) and China Telecom (3.4-3.5 GHz) under a small size is achieved.

Description

technical field [0001] This application relates to the technical field of smart wearable devices, in particular to a 5G dual-band MIMO antenna structure. Background technique [0002] With the birth of the fifth generation (5G) wireless communication technology, in the future, more and more handheld devices, including smart wearables, will use 5G communication technology to bring people a better Internet experience. The main frequency bands used by 5G networks are divided into microwave frequency bands below 6G and millimeter wave frequency bands above 6G. Compared with millimeter waves, microwaves are easier to implement for civilian use at this stage. Through MIMO (Multiple-Input Multiple-Output, Multiple-Input-Multiple-Output) technology, the purpose of greatly increasing the transmission rate can be achieved. [0003] In the 5G era, in order to achieve high-speed data transmission, at least four antennas that can cover the 5G frequency band are required. However, limite...
