Abstract
The disclosure relates to an antenna self-capacitance change detection method and apparatus, and related applications. The method includes: acquiring a total self-capacitance change of the antenna and a total self-capacitance change of the sensor electrode respectively; determining a first self-capacitance change of the antenna caused by a temperature change according to the total self-capacitance change of the sensor electrode and a preset self-capacitance change proportional coefficient; and determining a difference value between the total self-capacitance change and the first self-capacitance change of the antenna as a second self-capacitance change of the antenna caused by proximity of an object. The antenna self-capacitance change detection method can accurately determine the antenna self-capacitance change caused by the proximity of the object, to accurately determine whether there is an object approaching, thereby better controlling and adjusting the antenna transmitting power.
