Abstract

The invention provides an antenna system which comprises a system ground unit, a metal back casing, a frame serving as an antenna radiator, a grounding line, a feeder line and a tuning switch. The antenna radiator comprises a main radiator and a sub-radiator. The main radiator comprises a first main radiator which forms a first main slit with the metal back casing, a second main radiator which extends from the first main radiator and forms a second main slit with the metal back casing, and a first fracture which divides the first main radiator into two parts. The sub-radiator comprises a first sub-radiator which forms a first sub-slit with the metal back casing, a second sub-radiator which extends from the first sub-radiator and forms a second sub-slit with the metal back casing, and a second fracture which divides the first sub-radiator into two parts. Compared with the related art, the antenna system provided by the invention has the advantages of wide frequency band, high efficiency and good overall appearance.

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...
