GPS Antenna Basics
This page covers GPS Antenna basics.It mentions GPS Antenna application note and GPS Antenna manufacturers.
Antenna is basically a electro-magnetic signal transmitter and receiver device which transmits signal to the air and receives signal from the air respectively. GPS Antenna works at GPS frequencies. The main type of antennas used for GPS applications are of patch and helix type. Refer Helix vs Patch antenna and types of antenna for more information.
