Abstract:
1. An adjustment module for adjusting an antenna module, the antenna module is located in an electronic device for radiating a wireless signal, the adjustment module comprising: a monitoring module electrically connected to the antenna module for detecting an alternating current signal waveform when the antenna module radiates the wireless signal; a determining module electrically connected to the monitoring module for receiving the alternating current signal waveform, and generating an adjusting voltage value when the alternating current signal waveform is a non-constant amplitude, wherein the determining module further generates a regular voltage value when the alternating current signal waveform is a constant amplitude, for keeping the capacitance value of the capacitance adjusting unit; and a capacitance adjusting unit electrically connected to the determining module and the antenna module for changing a capacitance value according to the adjusting voltage value to adjust a resonance point coordinate of the antenna module.
