Abstract

The embodiment of the invention discloses an antenna adjustment method and device and a computer storage medium, the method is applied to a mobile terminal at least comprising a first antenna and a second antenna, and network parameters of the mobile terminal in a communication process are acquired in real time; wherein the network parameters at least comprise a working frequency band of a first antenna and a working frequency band of a second antenna; a working scene of the mobile terminal is determined according to the network parameters; if the determined working scene is that the mobile terminal works in a frequency band concurrent mode, the antenna efficiency of the first antenna at a harmonic interference frequency point is reduced, wherein the harmonic interference frequency point is obtained according to the interference of the first antenna to the second antenna, and a frequency band concurrent mode exists between the working frequency band of the first antenna and the workingfrequency band of the second antenna; therefore, the problem of signal interference caused by a frequency band concurrent mode can be effectively solved, and meanwhile, the antenna performance is also improved.

Description

Technical field [0001] The present invention relates to the field of communication technology, and in particular to an antenna adjustment method, device and computer storage medium. Background technique [0002] With the rapid development of mobile communication technology, the communication frequency bands supported by mobile phones and other terminals continue to increase, which greatly increases the difficulty of terminal antenna design. It is difficult to achieve high antenna efficiency and high isolation for all communication frequency bands supported by the terminal. Especially when there are concurrent scenarios in the radio frequency signals of two communication frequency bands and the harmonic frequency of one frequency band is in the frequency band of the other frequency band, the signal interference is caused. [0003] At present, the above problems have become more prominent. The existing solutions are to reduce harmonic energy by selecting switches and other radio freq...
