The Outdoor Marine Antenna Active GPS Beidou Antenna Instruction:
GPS Beidou antenna
GPS Beidou antenna is an antenna used to receive Beidou satellite signals.
GPS Beidou Antenna Classification
⒈ From the polarization mode, the Beidou antenna is divided into vertical polarization and circular polarization.
The effect of polarization is not as good as circular polarization. Therefore, except for special circumstances, the Beidou antenna will use circular polarization.
⒉ From the placement method, Beidou antennas are divided into internal antennas and external antennas.
The assembly location of the antenna is also very important. Earlier handhelds mostly used fold-out antennas. At this time, the antenna is basically isolated from the inside of the whole machine, and EMI hardly affects it, and the satellite reception effect is very good.
With the trend of miniaturization, Beidou antennas are mostly built-in. At this time, the antenna must be above all metal components, and the inside of the shell must be electroplated and well-grounded, away from EMI interference sources, such as CPU, SDRAM, SD card, crystal oscillator, DC/DC.
The application of car navigation will become more and more common. And the car shell, especially the car explosion-proof membrane, will seriously hinder the Beidou signal. An external antenna with a magnet (that can be attached to the roof of the car) is very necessary for car GPS/Beidou navigation.
GPS Beidou Antenna Structure
The vast majority of Beidou antennas are right-handed polarized ceramic media, and their components are ceramic antennas, low-noise signal modules, cables, and connectors.
Among them, the ceramic antenna is also called the passive antenna, dielectric antenna, and PATCH, it is the core technology of the Beidou antenna. The signal-receiving ability of a Beidou antenna depends mostly on the composition of its ceramic parts.
The low noise signal module is also called LNA, which amplifies and filters the signal. The selection of its components is also very important, otherwise, it will increase the reflection loss of the Beidou signal and cause excessive noise.
The selection of cables should also be based on reducing reflections to ensure impedance matching.
