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. The selection of components is also very important, otherwise it will increase the reflection loss of GPS signal, resulting in excessive noise. Cable selection should also be based on reducing reflection to ensure impedance matching and minimize signal loss. High-quality coaxial cables are typically used, as they offer superior shielding to prevent electromagnetic interference (EMI) and ensure that the signal remains strong and clear over long distances. Connectors, being the interface between the antenna and the receiver, must be chosen carefully to ensure a secure and reliable connection that does not compromise signal integrity.
