The present 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 set on the mainboard. An electrical point, a fourth feed point, a third ground point, a fourth ground point, a first tuning switch, a second tuning switch, a first matching network, a variable capacitor, a third tuning switch, a fourth tuning switch, and the In the second matching network, the metal frame is divided into a first radiating part and a second radiating part on the bottom and a third radiating part and a fourth radiating part on the top. The antenna system provided by the present invention realizes the 2×2 MIMO mechanism of LTE low frequency, the 4×4 MIMO mechanism of LTE medium and high frequency, the 2×2 MIMO mechanism of Wi‑Fi2.4G and Wi‑Fi5G, and simultaneously supports the mainstream frequency bands described in GNSS , the 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...
