The ADFGP.50A.07.0100C is an embedded active GNSS dual stacked patch antenna engineered for high-precision positioning. It covers multiple GNSS bands, including GPS (L1/L2/L5), GLONASS (G1/G2/G3), Galileo (E1/E5a/E5b), and BeiDou (B1/B2a/B2b). The antenna features a dual-feed, dual-stacked patch design on a 50x50mm ground plane to ensure a low axial ratio and stable radiation patterns. Integrated LNAs and front-end SAW filters reduce out-of-band noise and protect the GNSS receiver from interference, making it ideal for demanding applications like UAVs, robotics, autonomous vehicles, and RTK systems.
