We know that many GPS locator devices today have GPS antennas built into them. Among other things, the role of the GPS receiving antenna is to transform the electromagnetic wave energy of the radio signal coming from the satellite into a current that can be ingested and applied by the receiver electronics.

GPS is a terminal for positioning or navigation by receiving satellite signals. The antenna must be used to receive the signal. GPS satellite signals are divided into L1 and L2, with frequencies of 1575.42MHZ and 1228MHZ respectively. L1 is an open civil signal, and the signal is circular polarization. The signal strength is about -166dBW, which is a relatively weak signal. These characteristics determine that special antennas should be prepared for the reception of GPS signals.

Antenna is an essential part of wireless transmission, in addition to our fiber optic, cable, network cable, etc. transmission of wired signals, as long as the use of electromagnetic waves in the air to propagate the signal, all need various forms of antenna.
