　　The main manufacturers that can independently produce GPS ceramic antennas are Da Gama Navigation, Jiaxing Jiali Electronics, Jiabang, Jiakang Electronics, and other manufacturers.

　　Most manufacturers purchase ceramic components from both domestic and foreign sources to design amplification circuits.

　　Super intelligent terminals are increasingly becoming the trend, and the narrow space places high demands on the size of accessories.

　　Originally, the domestic technology was only limited to 15 × Mature above 15, 10 × Above 10, basically mature. Can achieve a minimum of 7 × Around 7, the yield rate will be low.

　　The vast majority of GPS antennas are right-handed polarized ceramic media, consisting of ceramic antennas, low noise signal modules, cables, and connectors.

　　Ceramic antennas, also known as passive antennas, dielectric antennas, and PATCH, are the core technology of GPS antennas. The signal reception ability of a GPS antenna largely depends on the composition of its ceramic parts.

　　The low noise signal module, also known as LNA, is the part that amplifies and filters the signal. The selection of its components is also important, otherwise it will increase the reflection loss of GPS signals and cause excessive noise.
