Construction of GPS antenna
Apr 07, 2017

The majority of GPS antennas are right-polarized ceramic media, the components are: ceramic antenna, low noise signal module, cable, connector.

The ceramic antenna is also called passive antenna, dielectric antenna, PATCH, it is the core of GPS antenna technology. The signal acceptance ability of a GPS antenna depends largely on the ingredients of its ceramics.

The low noise signal module is also called LNA, which is the part of amplifying and filtering signals. The selection of components is also important, otherwise it will increase the reflection loss of GPS signals, and causing excessive noise.

The selection of cables should also be used to reduce reflection as the standard, to ensure the matching impedance.
