Abstract

The invention provides an antenna system and a mobile terminal. The antenna system includes a metal frame, a main board accommodated in the metal frame and a first feed point, a second feed point, a first ground point and a second ground point provided on the main board; the metal frame comprises a bottom frame, the bottom frame is divided into a first radiating portion located at a lower left corner and a second radiating portion located at a lower right corner by a fracture, the first antenna is formed by feeding of the first feed point, the second antenna is formed by feeding of the secondfeed point, the operating frequency of the first antenna may cover the LTE low frequency, the operating frequency of both the first antenna and the second antenna may cover the LTE medium and high frequency & 3.4-3.8 GHz & C band, and the first antenna and the second antenna can work together to form the 2 * 2 MIMO mechanism of working LTE medium and high frequency & 3. 4-3.8 GHz & C band. With multi-frequency, multi-mode, multi-band carrier aggregation, better communication performance can be achieved.

Description

【Technical field】 [0001] The present invention relates to the technical field of communication, in particular to an antenna system and a mobile terminal. 【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 products with metal shell and 3D glass screen have good texture and aesthetic feeling, so they are welcomed by many consumers. [0003] Terminal manufacturers' control of the length and thickness of mobile terminals, as well as the use of metal casings will...
