Product Description

25*25mm GLONASS GPS Navigation Tracker Antenna

Introduction:

⒈ GPS antennas are divided into vertical polarization and circular polarization in terms of polarization.

Vertical polarization is not as effective as circular polarization. Therefore, except for special cases, GPS antennas will use circular polarization and linear polarization.

⒉ GPS antennas are divided into built-in antennas and external antennas in terms of placement.
The mounting position of the antenna is also very important. Early GPS handsets mostly used eversion antennas. At this time, the antennas were basically isolated from the interior of the whole machine, and EMI hardly affected them, and the star collection effect was very good. With the trend of miniaturization, GPS antennas are mostly built-in. At this time, the antenna must be above all metal devices, and the shell must be plated and grounded well, away from EMI interference sources, such as CPU, SDRAM, SD card, crystal oscillator, DC/DC.GSM GPS Antenna.
The application of in-vehicle GPS will become more and more common. The car's casing, especially the car's explosion-proof membrane, has a serious obstacle to the GPS signal. An external antenna with magnets (that can be attached to the roof) is necessary for car GPS.GPS Antenna SMA.

3. In terms of power supply, it is divided into active and passive.GPS Antenna Fakra.
The external GPS is an active antenna, such as the Gamma GPS external antenna is basically an active antenna. That passive antenna does not contain LNA amplifier, just the antenna body.Inside GPS Antenna
