High-precision watch antenna

Abstract

The invention discloses a high-precision watch antenna in the technical field of communication. The watch antenna comprises a watch body, and is characterized in that an inner cavity of the watch bodyis provided with a watch main board, the surface of the watch main board is welded with a watch main board and a second feed network, the watch main board and the second feed network are arranged inbilateral symmetry about the axis of the watch main board, the top of the watch body is provided with a watch screen, the bottom of the watch screen is provided with a high-frequency antenna radiator,the high-frequency antenna radiator comprises a high-frequency arm I and a high-frequency arm II, the first high-frequency arm and the second high-frequency arm are laser-carved on the right side andthe rear side of the watch screen respectively, and the high-frequency arm I and the high-frequency arm II are arranged adjacent to each other. On the basis of the size of the original watch body, acircularly polarized antenna is adopted, and the antenna efficiency and the positioning precision are improved. According to the scheme, the antenna adopts an LDS scheme to realize dual-frequency circular polarization, and two 90-degree phase shift networks are integrated in the watch body to realize right-handed circular polarization.

Description

technical field [0001] The invention relates to the technical field of communications, in particular to a high-precision watch antenna. Background technique [0002] Previously, most of children's watches were based on ordinary GPS positioning, with uneven positioning capabilities and positioning accuracy ranging from tens of meters to hundreds of meters. Inaccurate positioning data leads to inaccurate control of children's behavior by parents, and even misunderstanding. [0003] On March 1, 2019, the country's first smart watch that supports Beidou high-precision positioning - Abacho Children's Smart Watch T1 officially opened online pre-sales. This is also the "software and hardware integration" Beidou high-precision positioning technology in smart electronics The first application on the product will promote the positioning ability of the electronic product industry to a new level.

AI Technical Summary

Problems solved by technology

[0004] Traditional children's antennas are generally linearly polarized antennas, and the value of the circularly polarized signal will drop by half. The antenna directivity is poor, and the antenna efficiency is low, which is difficult to meet the normal use of children.
