GPS antenna is a key component specially used to receive satellite signals of the Global Positioning System. Its core function is to efficiently convert weak electromagnetic wave signals transmitted by GPS satellites (such as the right-hand circularly polarized signal at the L1 frequency band of 1575.42MHz) into electrical signals for receivers to calculate positioning and navigation data.Classified by built-in signal amplifier:

• Active antenna: Requires power supply

• Passive antenna: No power supply needed
