Abstract

The invention provides an antenna system and a mobile terminal, and relates to the technical field of antennas. The antenna system is applied to a mobile terminal, and includes: a first metal arm and a second metal arranged on two end parts of a frame of one side edge of the mobile terminal; and a third metal arm arranged on the frame of the side edge and located between the first metal arm and the second metal arm. A first opening is arranged between the third metal arm and the first metal arm, and a second opening is arranged between the third metal arm and the second metal arm; a first end of the third metal arm is connected to the ground through a radio frequency front end matching circuit; and a second end of the third metal arm is connected to the ground through a first antenna matching circuit. The scheme of the invention solves the problem of poor antenna signal quality when mobile terminals at present use metal structures, realizes antenna signals of higher quality, and tuning is easy.

Description

technical field [0001] The present invention relates to the technical field of antennas, in particular to an antenna system and a mobile terminal. Background technique [0002] With the development of mobile terminals, their functions gradually become more complex, and the internal layout of corresponding mobile terminals becomes more and more compact. [0003] However, it is well known that, as an important component of a mobile terminal, the antenna system needs to avoid possible impacts between it and surrounding structures, which may affect antenna signals and reduce user experience. In particular, metal textured mobile terminals, which are loved by people recently, use more metal structures such as metal frames in such mobile terminals, which will lead to poor antenna signal quality and reduce user experience. Contents of the invention [0004] The invention provides an antenna system and a mobile terminal, which are used to solve the problem of poor antenna signal q...
