Currently, most GPS antennas are right-handed polarized ceramic media consisting of ceramic antennas, low-noise signal modules, cables, and connectors. Ceramic antenna, also known as passive antenna, dielectric antenna and patch, is the core technology of GPS Antenna. The reception ability of GPS antenna depends largely on its ceramic components. Low noise signal module, also known as LNA, is the part that amplifies and filters the signal.
