Abstract

The invention provides an antenna system and a mobile terminal. The antenna system, Include metal border, a main board accommodated in the metal frame and a first feeding point provided on the main board, second feed point, primary ground point, secondary ground point, third feed point, fourth feed point, a third ground point, a fourth ground point, a first tuning switch, a second tuning switch, afirst matching network, a variable capacitor, a third tuning switch, a fourth tuning switch, and the second matching network, wherein the metal frame is separated into a first radiating portion and asecond radiating portion located at the bottom and a third radiating portion and a fourth radiating portion located at the top. The antenna system provided by the invention realizes the 2*2 MIMO mechanism of the LTE low frequency and the 4*4 MIMO mechanism of the LTE medium and high frequency, and covers operating frequency of Wi-Fi 2.4 G and Wi-Fi 5G, while supporting the mainstream frequency band of the GNSS, and communication performance is better.

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...
