In step S101, the foldable mobile terminal is a mobile phone, a tablet computer, or other terminal device with an antenna, and the states of the foldable mobile terminal include an unfolded state and a folded state.
Specifically, referring to fig. 2 and 3, the foldable mobile terminal according to the embodiment of the present invention includes a first main body 10, a second main body 20, and a rotating shaft assembly 30, where the first main body 10 and the second main body 20 are connected by the rotating shaft assembly 30, the first main body 10 and/or the second main body 20 can rotate around the rotating shaft assembly 30 to make the foldable mobile terminal in an unfolded state (as shown in fig. 2) or a folded state (as shown in fig. 3), both the first main body 10 and the second main body 20 adopt flexible screens, and the rotating shaft assembly 30 is made of an aluminum alloy material.

In step S202, the magnetic induction between the magnetic sensor and the magnet is detected by the magnetic sensor.
When the foldable mobile terminal is in the folded state, the magnetic sensor 21 can sense the magnetic field of the magnet 11, and the magnetic induction intensity is relatively high, so that it can be determined that the first body 10 and the second body 20 are close to each other. When the foldable mobile terminal is in the unfolded state, the magnetic sensor 21 is no longer influenced by the magnetic field of the magnet 11, and the magnetic induction intensity is zero, so that it can be determined that the first body 10 and the second body 20 are away from each other. In the embodiment, the magnetic sensor 21 is a hall sensor, when the hall sensor is subjected to the action of a magnetic field, a hall element generates a tiny hall voltage, the hall voltage is in direct proportion to the magnetic induction intensity, the magnetic induction intensity is judged through the generated hall voltage, and then whether a magnet is close to the hall sensor can be judged; and when the detected magnetic induction intensity is greater than a preset threshold value, judging the state to be a folded state, and when the detected magnetic induction intensity is less than or equal to the preset threshold value, judging the state to be an unfolded state.

and acquiring the preset tuning parameters corresponding to the current state according to the corresponding relation between the preset tuning parameters stored in advance and the state of the foldable mobile terminal.

Specifically, the impedance tuner 50 includes a variable capacitor and is disposed in the main path of the feed point to optimize and adjust the impedance of the main path and improve the standing wave return loss of the antenna, the aperture tuner 60 controls the on-off state of different components by connecting a capacitor inductor to an aperture connection plane, the operating frequency of the antenna is improved, and the antenna resonance adjustment is realized by the impedance tuner 50 and the aperture tuner 60 together.
And step S402, when the current state is judged to be the expansion state, a first tuning parameter is obtained through the common tuning of the impedance tuner and the caliber tuner and is stored as a preset tuning parameter corresponding to the expansion state.
The impedance tuner 50 optimizes the impedance of the debugging main channel according to the unfolding state of the foldable mobile terminal, and the caliber tuner 60 controls the on-off state of different components, so that the tuning and the covering of the optimal antenna working frequency band are realized, and related tuning parameters are stored in a memory of the foldable mobile terminal.
And step S403, when the current state is judged to be the folding state, obtaining a second tuning parameter through the common tuning of the impedance tuner and the caliber tuner, and storing the second tuning parameter as a preset tuning parameter corresponding to the folding state.
According to the folding state of the foldable mobile terminal, the impedance tuner 50 optimizes the impedance of the debugging main channel, usually switches to a small capacitance parameter to tune the antenna impedance, meanwhile, the caliber tuner 60 switches the on-off state of different components, and further tunes the antenna resonance optimized by the impedance tuner 50 to the working frequency, so that the antenna working frequency band tuning, namely covering, is realized, the antenna signal in the folding state is improved, and related tuning parameters are stored in a memory of the foldable mobile terminal.
And step S103, adjusting the antenna tuning parameters of the foldable mobile terminal to preset tuning parameters.
