Examples
example 1
[0064] Example 1: Adjust the working frequency band of the antenna of the mobile terminal to a certain set working frequency band, and insert an earphone into the mobile terminal. Then, adjust the antenna tuner capacitance value, inductance value or number of switches, etc., and detect the working efficiency of the antenna of the mobile terminal. When it is tested that the working efficiency of the antenna of the mobile terminal is the highest, the capacitance value, inductance value or number of switches of the antenna tuner at this time is selected as the first matching state of the antenna tuner. The corresponding relationship between setting the working frequency band, inserting the earphone of the mobile terminal and the first matching state is recorded.
example 2
[0065] Example 2: Adjust the working frequency band of the antenna of the mobile terminal to a certain set working frequency band, and determine that the mobile terminal is not plugged into an earphone. Then, adjust the antenna tuner capacitance value, inductance value or number of switches, etc., and detect the working efficiency of the antenna of the mobile terminal. When it is tested that the working efficiency of the antenna of the mobile terminal is the highest, the capacitance value, inductance value or number of switches of the antenna tuner at this time is selected as the second matching state of the antenna tuner. Record the correspondence between the set working frequency band, the absence of earphones inserted into the mobile terminal, and the second matching state.
example 3
[0066] Example 3: Adjust the working frequency band of the antenna of the mobile terminal to a certain set working frequency band, and insert a USB interface device into the mobile terminal. Then, adjust the antenna tuner capacitance value, inductance value or number of switches, etc., and detect the working efficiency of the antenna of the mobile terminal. When it is tested that the working efficiency of the antenna of the mobile terminal is the highest, the capacitance value, inductance value or number of switches of the antenna tuner at this time is selected as the third matching state of the antenna tuner. The corresponding relationship between setting the working frequency band, inserting the mobile terminal into the USB interface device and the third matching state is recorded.
