Description

This compact embedded antenna is designed for high-precision GNSS applications, supporting GPS, GLONASS, Galileo, and QZSS systems. With a pre-filter and 28 dB active gain, it delivers low noise and reliable signal reception, making it ideal for integration into space-constrained devices. Its ground plane independence and low power consumption make it suitable for consumer electronics, robotics, drones, smart farming, asset tracking, and more.
