Off-the-Shelf Antennas for Controlled-Reception-Pattern Antenna Arrays
The antenna is a critical component of any GNSS receiving equipment. It must be carefully designed for the frequencies and structures of the signals to be acquired and tracked. Important antenna properties include polarization, frequency coverage, phase-center stability, multipath suppression, the antenna’s impact on receiver sensitivity, reception or gain pattern, and interference handling. While all of these affect an antenna’s performance, let’s just look at the last two here.
