Introduction
A GPS Active Ceramic Patch Antenna is a high-performance antenna designed to receive satellite signals and provide accurate location and navigation. These antennas combine a ceramic patch element with an inbuilt Low Noise Amplifier (LNA), resulting in strong signal reception even in low-signal settings.
They are commonly employed in automotive, IoT, telematics, drones, and tracking systems, where precision and dependability are essential.
