Compact Size: The small, flat form factor makes it easy to integrate into portable devices like handheld GPS units, drones, and automotive systems.
Wide Bandwidth: GPS patch antennas are designed to work across a wide frequency range, typically in the L1 band (1575.42 MHz), the standard frequency for GPS signals.
Polarization: They usually have a circular polarization, which helps in reducing the signal degradation due to multipath effects (signals that bounce off nearby objects).
