Description
This compact, passive GNSS patch antenna is designed for high-precision L1/L2 positioning in space-constrained devices. Its stacked ceramic patch construction helps deliver strong directional performance for fast positioning and reliable navigation across key GNSS constellations.
- Multi-constellation support: GPS, GLONASS, Galileo and BeiDou coverage
- Compact form factor: suited to small navigation and tracking devices
- Optimized integration: tuned and tested on a 70 x 70mm ground plane for excellent radiation patterns
Typical applications include: Wearables, Transportation, Precision Agriculture, Navigation, Security, Autonomous Vehicles.
Installation / Environmental
The following is an example on how to integrate the HP2258.A into a design. The HP2258.A has one pin which is used for the RF Feed. The manufacturer recommends using a minimum of 70x70mm ground plane to ensure optimal performance.
