Description
This embedded stacked passive patch antenna is designed for dual-band satellite navigation, supporting GPS L1/L2 and Galileo E1. Its dual-feed, dual-pin stacked patch design helps achieve a low axial ratio and stable radiation performance for reliable positioning, even in challenging signal environments.
- Dual-band GNSS support: GPS L1/L2 and Galileo E1
- Stacked patch architecture: engineered for strong performance and stability
- Compact embedded form factor: suited to space-constrained device designs
- Designed for integration: tuned on a 70 x 70 mm ground plane
Typical applications include:
- High accuracy positioning and navigation systems
- UAVs, Robotics & Autonomous Vehicles
- Mapping & GIS
- Transportation & Telematics
- Precision Agriculture
- Public Safety, Search & Rescue
- RTK Systems
Also available as GPDF357B tuned specifically for a smaller 35 x 35 mm ground plane.
