Abstract

Provided is an antenna system, including a system ground unit, a metal back cover, a frame as antenna radiator, and a grounding circuit, a feeding circuit and a tuning switch, the antenna radiator includes a main radiator and an auxiliary radiator; the main radiator includes a first main radiator which forms, together with the metal back cover, a first main gap, a second main radiator extending from the first main radiator and forms, together with the metal back cover, a second main gap, and a first fracture separating the first main radiator into two parts; the auxiliary radiator includes a first auxiliary radiator which forms, together with the metal back cover, a first auxiliary gap, a second auxiliary radiator extending from the first auxiliary radiator and forms, together with the metal back cover, a second auxiliary gap, and a second fracture separating the first auxiliary radiator into two parts.

Description

technical field [0001] The invention relates to an antenna, in particular to an 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 communica...
