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 feeding point, a second feeding point, a first grounding point, a second grounding point, and a third feeding point arranged on the main board. electric point, the fourth feed point, the third ground point, the fourth ground point, the first tuning switch, the second tuning switch, the first matching network, the variable capacitor, the third tuning switch, the fourth tuning switch and the In the second matching network, the metal frame is divided into a first radiation part and a second radiation part at the bottom and a third radiation part and a fourth radiation part at the top. The antenna system provided by the present invention realizes the 2×2 MIMO mechanism of LTE low frequency and the 4×4 MIMO mechanism of LTE medium and high frequency, covers the working frequency of Wi-Fi2.4G and Wi-Fi5G, and supports the mainstream frequency band mentioned in GNSS at the same time, 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...
