Most of GPS antennas are right-handed polarized ceramic media, and its components are: Ceramic Antenna, low noise signal module, cable, connector.
The ceramic antenna is also called passive antenna, dielectric antenna and PATCH, which is the core technology of GPS antenna. The ability of a GPS antenna to receive signals depends largely on the composition of its ceramic parts. The low noise signal module, also known as LNA, is the part of the signal that is amplified and filtered. Its component selection is also very important, otherwise it will increase the reflection loss of GPS signal, and cause too much noise.
