Embedded Stacked Passive GPS Patch Antenna
The Taoglas GPDF357A is a precision-engineered embedded GPS stacked passive patch antenna supporting both GPS L1/Galileo E1 and GPS L2 bands. The stacked, two-pin feed design, consists of two patches, the bottom patch measuring 35*35*4mm and the top patch at 25*25*3mm, each patch with one pin feed, resulting in compact dimensions of just 35*35*7.15mm. The antenna has been tuned and tested on a 70*70mm ground plane, specifically for GPS L1/Galileo E1 at 1575.42MHz and GPS L2 at 1227.6MHz.
Utilizing two patches ensures that a low axial ratio can be achieved. The antenna exhibits excellent gain and good radiation pattern stability leading to a reliable GNSS fix, even in areas of weaker signal strength. All these elements combined can ensure the best possible positional accuracy for your device. The GPDF357A is manufactured and tested in a TS16949 first tier automotive approved facility.
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 smaller 35*35mm ground plane, the GPDF357B. Patch antennas can also be tuned to customer-specific device environments, subject to NRE and MOQ. Contact your regional Taoglas customer support team to request these services or additional support to integrate and test this antenna’s performance in your device.
