GPDF357B Antenna GNSS embedded patch for High accuracy positioning and navigation systems, UAVs, Robotics & Autonomous Vehicles, Mapping & GIS, Transportation & Telematics

Embedded stacked passive GNSS patch antenna designed for compact, high-performance positioning devices. This dual-pin stacked patch design supports GPS L1 and L2 along with Galileo E1, helping deliver reliable satellite reception and improved positioning performance in challenging environments.

• Dual-pin stacked patch design: supports multi-band GNSS operation
• Low axial ratio: supports stable RHCP performance for GNSS reception
• Optimized for integration: intended for embedded device platforms using a defined 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

This patch can also be purchased in a version tuned specifically for a larger 70*70mm ground plane, the GPDF357A. Patch antennas can also be tuned to customer-specific device environments, subject to NRE and MOQ. Contact your regional customer support team to request these services or additional support to integrate and test this antenna’s performance in your device.
