Description

technical field [0001] The application belongs to the technical field of communication, and in particular relates to an antenna tuning method, an antenna tuning device, terminal equipment and a computer. Background technique [0002] With the full-screen design of mobile terminals and the continuous and in-depth development of 5G communication technology, the performance challenges faced by antennas built into mobile terminals are becoming more and more severe. In order to make the performance of the antenna reach the best tuning as much as possible, before the mobile terminal leaves the factory, the performance of the antenna needs to be debugged. [0003] The traditional antenna debugging method is to debug the performance of the antenna through the test of several single scenarios, for example, when the antenna is tested in a free space and has a head-hand model with specific parameters (the head-hand model with specific parameters is mainly simulated The specific state o...
