Classification Of GPS Antenna

From the GPS antenna on the polarization into vertical polarization and circular polarization.

With today's technology, vertical polarization effects than circular polarization. Except in special cases, GPS antenna with circular polarization and linear polarization.

Place the GPS antenna on the way divided into internal and external antennas.

The Assembly position of the antenna is also very important. Early GPS handsets use eversion-type antennas, antenna and internal isolation, EMI almost does not affect collecting star works well. Now, with the miniaturization trend, GPS antenna built-in. This antenna must be at the top all metal components, shell plating and well grounded, away from EMI interference sources, such as CPU,SDRAM,SD cards, Crystal, DC/DC.

Car GPS will become more and more common. And the shell of the car, especially serious obstacles for the car explosion-proof membrane GPS signals. A magnet (can be adsorbed onto the roof) external antenna for car GPS is very necessary.
