Problems solved by technology

With the development of the fifth-generation mobile communication system 5G, it is necessary to deploy 5G in two C-Band frequency bands, and it is necessary to use 4*4 or even 8*8 MIMO antenna design. In the existing antenna system, the metal frame is limited. The number of cracks and the limited space make it difficult to achieve the relevant requirements for good performance and isolation after the layout of multiple antenna structures

Abstract

The invention provides an antenna system, comprising a system ground unit having a feed point, a metal frame disposed adjacent to the system ground unit, a grounding line extending from the metal frame to the system ground unit and forming a grounding connection, and a first antenna and a second antenna at least having the metal frame as a partial radiator, wherein the metal frame is spaced apartfrom the system ground unit to form a clearance area; the first antenna and the second antenna are electrically connected to the feed point of the system ground unit respectively, and are respectivelydisposed at both sides of the grounding line in a spaced manner and radiate orthogonal modes. Compared with the related art, the antenna system of the invention has a wide frequency band, a good overall aesthetic appearance and high strength.

Description

technical field [0001] The invention relates to an antenna, in particular to a MIMO antenna system used in the field of communication electronic products. Background technique [0002] With the development of mobile communication technology, mobile phones, PADs, notebook computers, etc. have gradually become indispensable electronic products in daily life, and these electronic products have been updated to electronic communication products that add antenna systems to enable communication functions. However, consumers are no longer only satisfied with their application functions, and their requirements for the appearance of the electronic communication products are also constantly increasing. The electronic communication product with a metal casing has a good texture and is durable, so it is welcomed by many consumers. [0003] Because electromagnetic waves cannot penetrate metal, it is not conducive to the radiation of the antenna system. When designing the electronic commu...
