GNSS antenna system of mobile terminal and mobile terminal

Abstract

The invention discloses a GNSS antenna system of a mobile terminal and the mobile terminal. The system comprises a GNSS master antenna, a GNSS diversity antenna, a first positioning processor and a second positioning processor, wherein the GNSS master antenna is used for generating a first positioning signal; the GNSS diversity antenna is used for generating a second positioning signal; the first positioning processor is used for processing a first positioning signal; the second positioning processor is used for processing the second positioning signal; and at least one of the GNSS master antenna and the GNSS diversity antenna is a microstrip antenna. According to the system, at least one of the GNSS master antenna and the GNSS diversity antenna is designed through the microstrip antenna, so that the structural design difficulty is lowered; and the trouble of installing an antenna bracket on a mainboard of the mobile terminal is avoided. The positioning signals are received through the GNSS master antenna and the GNSS diversity antenna, so that deterioration of received signals caused by spatial fading and the like can be effectively suppressed; and the signal-to-noise ratio of each signal is improved.

Description

technical field [0001] The invention relates to the technical field of mobile terminals, in particular to a GNSS antenna system for a mobile terminal and a mobile terminal. Background technique [0002] At present, antenna diversity technology, especially mobile terminal (such as mobile phone) antenna diversity technology, has been widely used in LTE diversity 4G communication. The diversity antenna and the main antenna are located at different positions of the mobile terminal and have different antenna forms. It can be understood that the main antenna and the diversity antenna are two non-correlated signal receiving devices, and the combination of the main antenna and the diversity antenna can effectively suppress the deterioration of the received signal due to spatial fading and improve the signal-to-noise ratio. [0003] With the development of wireless communication technology, the functions of mobile terminals are becoming more and more abundant. In addition to basic vo...

AI Technical Summary

Problems solved by technology

[0004] The current mobile phone manufacturing is increasingly pursuing the thinning and thinning of mobile terminals. In order to meet the requirements of smaller and smaller wireless data terminals, the area of ​​the PCB board is also decreasing. The main antenna, diversity antenna and WIFI antenna are installed on the PCB board. The location of the antenna is becoming more and more difficult to arrange, and due to the small distance, there will be signal interference between the antennas, resulting in the service quality of the business cannot be guaranteed
