Description

technical field [0001] The invention relates to the field of electronic equipment, in particular to the field of electronic equipment with wire devices. Background technique [0002] In recent years, the use of electronic devices such as mobile phones, tablet computers, and wearable devices has become increasingly popular. However, in terms of the quality of received signals and ensuring positioning accuracy of satellite positioning antennas for electronic devices, they still cannot fully meet the needs of users. [0003] For example, for mobile phones, due to the increase of mobile phone antennas, the space of mobile phones is limited, and mobile phone GNSS (Global Navigation Satellite System, Global Navigation Satellite System) antennas generally adopt the form of monopole or IFA antennas, and the polarization mode is generally Linear polarization; on the other hand, GNSS satellite signals are circularly polarized, resulting in a loss of receiving polarization efficiency, ...

Problems solved by technology

[0002] In recent years, the use of electronic devices such as mobile phones, tablet computers, and wearable devices has become increasingly popular, but in terms of the quality of the received signal of the satellite positioning antenna of the electronic device, ensuring the positioning accuracy, etc., it still cannot fully meet the needs of users

[0003] For example, for mobile phones, due to the increase of mobile phone antennas, the space of mobile phones is limited, and mobile phone GNSS (Global Navigation Satellite System, Global Navigation Satellite System) antennas generally adopt the form of monopole or IFA antennas, and the polarization mode is generally Linear polarization; on the other hand, GNSS satellite signals are circularly polarized, resulting in a loss of receiving polarization efficiency, which directly limits the improvement of satellite positioning accuracy, especially for high-precision RTK (Real-time kinematic, real-time dynamic) positioning to form constraints

[0004] On the other hand, although professional GNSS communication electronic equipment antennas use dielectric ceramics or four-arm helical antennas to achieve circular polarization, there is a problem of too large volume, which cannot be well applied to communication electronic equipment that requires high volume.
