[Technical Field] This utility model relates to the field of antenna technology, and in particular to a GNSS antenna suitable for smart meters. [Background Technology] With the rapid development of intelligent electronic products, electricity meters are also becoming increasingly intelligent. Currently, most electricity meters on the market rely on manual recording or use simple GPS modules, which suffer from high costs and signal blockage, resulting in inaccurate positioning accuracy. [Utility Model Content] To overcome the above problems, this utility model proposes a GNSS antenna suitable for smart meters that can effectively solve the above problems.
[0001] The present invention provides a technical solution to solve the above-mentioned technical problems: a GNSS antenna suitable for smart meters, comprising a PCB board and a copper sheet antenna. The PCB board has multiple copper-plated circuit areas, and the copper sheet antenna is soldered to these areas. The copper sheet antenna includes a plate-shaped main antenna with a perforated strip-shaped hole in its center. A feed point is located on one side of the perforated strip-shaped hole, and the feed point is connected to the PCB board via a feed strip. The plate-shaped main antenna is rectangular, with feed angles vertically connected to its four corners and to the center of its four sides. There are eight feed angles in total. The number of copper-plated circuit areas is also eight, with each copper-plated circuit area corresponding to one feed angle, and the feed angle is soldered to its corresponding copper-plated circuit area. Preferably, the end of the feed angle is provided with a welding angle perpendicularly, and the welding angle is welded to the copper-paved circuit area.
[0002] Preferably, the PCB board is provided with a power supply hole, and the power supply point is soldered to the power supply hole through a power supply strip.
[0003] Preferably, the PCB board is made of F4B PCB material and copper etching process.
[0004] Preferably, the shape and size of the PCB board match the shape and size of the copper sheet antenna.
[0005] Preferably, the PCB board and the copper antenna are provided with beveled corners at all four corners.
[0006] Compared with existing technologies, the GNSS antenna of this invention for smart meters adopts a composite structure of PCB substrate and copper sheet, which balances cost and radiation efficiency, optimizes circular polarization design, reduces multipath interference, and improves positioning stability.
