　　1. GPS antenna can be divided into vertical polarization and circular polarization in terms of polarization mode. With current technology, the effect of vertical polarization is not as good as that of circular polarization. Therefore, except for special cases, the GPS antenna will adopt circular polarization.

　　2. GPS antenna can be divided into internal antenna and external antenna in terms of placement mode. The assembly position of the antenna is also very important. In the early days, most GPS handsets used an everted antenna. At this time, the antenna was basically isolated from the interior of the whole machine, and EMI hardly affected it. The satellite receiving effect was very good. Now, 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 well grounded, away from EMI interference sources, such as CPU, SDRAM, SD card, crystal oscillator, DC/DC.

　　The application of vehicle GPS will become more and more popular. However, the shell of the car, especially the explosion-proof membrane of the car, will seriously hinder the GPS signal. An external antenna with a magnet (which can be attached to the roof) is very necessary for on-board GPS.
