An antenna adjusting method and an antenna system terminal

Abstract

The invention provides an antenna adjusting method and an antenna system terminal, the antenna adjusting method is applied to the antenna system terminal, and the antenna system terminal comprises a diversity antenna and a positioning antenna; The antenna adjusting method comprises the steps of obtaining communication parameters of the antenna system terminal, wherein the communication parametersat least comprise an impedance value, a low-frequency resonance point and an intermediate-frequency resonance point; Regulating and controlling a low-frequency resonance point of the antenna system terminal so as to reduce the bandwidth of the low-frequency resonance point; Adjusting and controlling an impedance value of a low-frequency resonance point of the antenna system terminal so as to reduce the frequency point efficiency of the positioning antenna; Wherein by controlling the impedance value of the antenna system terminal, the bandwidth of the low-frequency resonance point is regulatedand controlled, and the second harmonic energy generated by a communication channel is reduced; Through the antenna control method, the interference of second harmonic energy on the positioning systemcan be reduced, the sensitivity of the positioning system is improved, and the accuracy of the positioning system is improved.

[0003] In the prior art, GPS (Global Positioning System, Global Positioning System) is applied to user mobile phones and other mobile terminals, and mobile phone GPS navigation has also become the mainstream of self-driving navigation, personal travel, etc.; but the sensitivity of GPS is relatively high. There are similar interference signals in the band, which will interfere with the performance of GPS, resulting in a decrease in accuracy; therefore, the positioning accuracy of mobile phone GPS technology will directly affect the user experience

[0004] AGPS (Assisted Global Positioning System, Assisted Global Positioning System) is an operation mode of GPS. It mainly uses the signal resources of mobile phone base stations and cooperates with traditional GPS satellite positioning technology to make GPS positioning faster; however, AGPS positioning The technology is mainly through the communication of the main radio frequency of the mobile terminal, which will involve the passage of LTE B13 / 14, and the second harmonic of the B13 / 14 will fall within the GPS frequency, causing interference to GPS performance, resulting in attenuation of GPS sensitivity, making Inaccurate or even impossible to locate
