HP25258 – Passive Multi-band GNSS (L1/L2/L5) 25 x 25 x 8 mm Stacked Patch Antenna

Ultra-Compact 25 × 25 mm Multi-Band GNSS Patch Antenna

The Taoglas HP25258.A is one of the smallest high-precision multi-band patch antennas available, delivering full L1, L2, and L5 GNSS coverage in an ultra-compact 25 × 25 mm footprint with a height of just 8 mm. Designed for applications where every millimeter counts, it combines minimal size with exceptional performance, enabling high-accuracy positioning across GPS, Galileo, BeiDou, QZSS, and IRNSS, as well as support for SBAS augmentation services.

Despite its compact size, the HP25258.A achieves stable gain, high efficiency, and RHCP polarization across all three bands, ensuring consistent reception even in obstructed or multipath-prone environments. Its single-feed design simplifies integration without compromising multi-band performance, while the pin-mount structure and optimization for a 70 × 70 mm ground plane make it easy to embed in a wide range of space-constrained platforms.

Typical applications include:

• Surveying and Precision Agriculture
• Unmanned Aerial Vehicles (UAVs) and Robotics
• Automotive Telematics and Navigation
• Industrial IoT and Asset Tracking
• Timing and Synchronization Systems

Engineered for demanding environments, the HP25258.A operates from -40°C to +105°C, is RoHS and REACH compliant, and built with a durable ceramic structure for long-term stability. With its super-small 25 mm footprint and triple-band precision performance, the HP25258.A is the ideal choice for next-generation GNSS solutions where space and accuracy are equally critical.
