Compact Full-Band Embedded Helix Antenna for UAVs

Key Features

• Consistent Performance across Full Frequency Bands

  The HX-HE401A supports GPS, GLONASS, Galileo, BeiDou, QZSS, and L-band correction services, delivering consistent full-band satellite tracking and reliable high-precision positioning performance for UAV navigation across complex and demanding flight environments.

• High Phase Center Stability and Consistent Performance

  Multi-point feeding technology provides high phase center stability with centimeter-level repeatability, while high peak gain and excellent axial ratio enable effective multipath mitigation and maintain a precise phase center for consistent high-precision positioning performance.

• Small Form Factor, Light Weight, Designed for Integration

  High gain and a wide radiation beam enable excellent reception and tracking of low-elevation satellite signals, helping maintain accurate and reliable high-precision positioning under tree canopies, near buildings, and in other challenging environments with limited satellite visibility.

• Tracking in Challenging Environments

  Measuring only Φ45 × H39.8 mm and weighing ≤10 g, the HX-HE401A minimizes overall UAV payload while enabling easy integration into lightweight platforms, helping improve flight endurance while maintaining reliable positioning performance for demanding UAV applications.
