Embodiments of this application disclose a variable capacitor-based antenna adjustment method and a related apparatus. A first signal strength of a first communications system with a highest priority that is supported by an antenna having a variable capacitor is detected, and when the first signal strength is relatively strong to meet a first release condition, a capacitance value of the variable capacitor is adjusted to a preset capacitance value, where the preset capacitance value is closer to a second capacitance value corresponding to a working frequency band of a second communications system supported by the antenna, so that a working frequency band of the antenna having the variable capacitor is closer to the working frequency band of the second communications system, and therefore, communication quality of the second communications system is improved. Although the first signal strength is attenuated, because the first signal strength is very strong before the attenuation, the attenuated first signal strength can still meet a communication quality requirement on the first communications system. Therefore, this application can give consideration to communication quality of multiple systems supported by the antenna having the variable capacitor.
Description
technical field [0001] The present application relates to the technical field of communications, and in particular to a variable capacitance-based antenna adjustment method and a related device. Background technique [0002] With the development of communication technology, communication systems using different wireless communication technologies have emerged one after another, such as Global System for Mobile communication (GSM) using Time Division Multiple Access (TDMA) technology, and Code Division Multiple Access (CDMA) technology. A voice communication system using Code Division Multiple Access (CDMA) technology, a data communication system using Long Term Evolution (Long Term Evolution, LTE) technology, etc. Different communication systems correspond to different working frequency bands. In order to enable mobile terminals to support different communication systems, the antennas of mobile terminals are required to cover a wider working frequency band in order to meet t...
