Abstract

The invention discloses an antenna system, a mobile terminal and an antenna tuning control system. The antenna system comprises a parasitic antenna and an antenna feed point, and also comprises a top metal routing, a high frequency tuning module and a low frequency tuning module, wherein the top metal routing is used as the radiation body of the antenna system, wherein the distance from the top metal routing to the top frame is less than a first preset distance, and in addition, the top metal routing and an all-metal back cover are insulated; the high frequency tuning module is positioned on a PCB of the mobile terminal, connected with the parasitic antenna, and used for tuning the high frequency signals of the antenna system, wherein the PCB is used as the reference ground of the mobile terminal and electrically connected with the all-metal back cover; and the low frequency tuning module is positioned on the antenna feed point and used for tuning the low frequency signals of the antenna system. According to the technical scheme provided by the invention, the purpose of improving the communication effect of the mobile terminal under the premise that the mobile terminal adopts the all-metal back cover is fulfilled.

Description

technical field [0001] The invention relates to the technical field of antenna design, in particular to an antenna system, a mobile terminal and an antenna tuning control system. Background technique [0002] Currently, more and more mobile terminal manufacturers have launched their own terminal products with metal back covers to meet consumers' current requirements on the appearance of mobile terminals. [0003] In order not to affect the communication signal of the terminal, the metal back cover of most existing mobile terminals is not an all-metal one-piece back cover, but is divided into multiple metal covers, and each metal cover is isolated. And the metal cover in the lower section acts as an antenna radiator to ensure that the terminal has sufficient communication capabilities. Of course, there are also mobile terminals with all-metal back covers at present, but such mobile terminals have signal problems such as poor communication signals and inability to meet signal...
