[0003] However, this method has certain requirements for the coupling distance between the antenna unit and the metal frame. When the display screen of the mobile terminal adopts a curved screen, the glue position of the curved screen will occupy the coupling space between the antenna unit and the metal frame. , therefore, it is easy to cause the coupling excitation effect between the antenna unit and the metal frame to deteriorate, thereby reducing the radiation performance of the antenna system
In addition, the clearance area on the motherboard will also have a certain impact on the coupling excitation between the antenna unit and the metal frame
Specifically, the smaller the clearance area on the main board, the more metal components are arranged on the main board. These metal components are likely to cause poor coupling and excitation effects between the antenna unit and the metal frame, thereby reducing the radiation of the antenna system. performance

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] At present, when designing an antenna system for a mobile terminal with a metal frame, the RF feed terminal on the motherboard is often used to excite the antenna unit as the first radiator of the antenna system, and then the antenna unit is indirectly coupled with the metal frame, so that the metal frame As the second radiator of the antenna system, the two radiators work together to make the resonance generated by the antenna system meet the bandwidth requirement. [0003] However, this method has certain requirements for the coupling distance between the antenna unit and the metal frame. When the display screen of the mobile terminal adopts a curved screen, the glue position of the curved screen will occupy the coupling space between the antenna unit and the metal frame. , therefore, it is ea...
