Embodiment 1

[0032] This embodiment provides a method for automatically adjusting antenna parameters, which is applied to mobile terminals with antennas, such as figure 1 shown, including the following steps:

[0033] S10: Obtain a signal transmission frequency.

Abstract

The invention discloses an antenna parameter automatic adjusting method, an antenna parameter automatic adjusting device, and an antenna parameter automatic adjusting antenna. The antenna parameter automatic adjusting method is characterized in that signal emission frequency is acquired; equivalent impedance required by an antenna adjusting circuit is calculated under the signal emission frequency; the impedance value of the antenna adjusting circuit is adjusted to be equal to the equivalent impedance. The parameters of the emission antenna can be adjusted automatically according to the signal emission frequency in the actual use, and the resonance frequency of the antenna is matched with the signal emission frequency, and therefore during the resonance of the antenna under the above mentioned frequency, the impedance of the antenna is smallest, the efficiency of the antenna is highest, the standing-wave ratio of the antenna is smallest, the power consumption of the antenna is smallest, and the signal of the antenna is strongest.

Description

technical field [0001] The invention relates to the field of antennas, in particular to an antenna parameter automatic adjustment method, device and antenna. Background technique [0002] In different countries, the frequency bands occupied by mobile terminal networks such as mobile phones will be different. For example, the GSM network in the United States uses 850MHz and 1900MHz, while the GSM network in my country uses 900MHz and 1800MHz. Due to the surge in the number of mobile terminal users, the mobile terminal communication network system will be in an overloaded state, and eventually the mobile terminal is prone to failures such as dropped calls, crosstalk, poor voice quality, and difficulty accessing the Internet during communication. In order to further expand the operating capacity of the mobile terminal network system and improve the voice quality of the mobile terminal communication, the mobile terminal network uses more than one frequency band. The mobile term...
