Abstract

Embodiments of the present invention provide an antenna tuning matrix unit, a radiation spurious control device, a method, and a mobile terminal. The antenna tuning matrix unit is connected to an antenna radiation unit, and a resonant circuit is arranged in the antenna tuning matrix unit. The resonant frequency of the resonant circuit satisfies a preset relationship with the working frequency of the antenna radiating unit. In the embodiment of the present invention, a resonant circuit is provided in the antenna tuning matrix unit. When the resonant circuit resonates, it can reflect the resonant wave corresponding to the resonant frequency, and reduce the radiation efficiency generated when the antenna radiation unit is working, so that the resonant wave cannot be radiated out, thereby reducing the Radiation spurious effects.

Description

technical field [0001] The invention relates to the technical field of mobile terminals, in particular to an antenna tuning matrix unit, a radiation spurious control device, a method and a mobile terminal. Background technique [0002] At present, most mobile terminals with an all-metal middle frame and a back cover use the middle frame of the mobile terminal as an antenna, and transmit signals through the antenna. [0003] However, due to the parasitic effect of the distribution parameters of each device in the mobile terminal, there may be a problem that the mobile terminal may not meet the certification requirements of the RSE standard when the mobile terminal transmits signals through the antenna. Contents of the invention [0004] Embodiments of the present invention provide an antenna tuning matrix unit, a radiation spurious control device, a method, and a mobile terminal, so as to solve the problem of excessive radiation spuriousness when the mobile terminal transmi...
