Maxtena Inc. has introduced an advanced, tiny, patented GNSS antenna for high-precision and autonomous multi-frequency applications. The M9HCT-A-SMA antenna is a high-precision, multi-frequency active helix GNSS antenna + L-band correction services.

The design offers simultaneous GNSS reception in a rugged, compact and ultra-light form factor on:

  • L1: GPS, GLONASS, Galileo, Beidou
  • L2: GPS L2C, Galileo E5B, GLONASS L3OC
  • L5: GPS + L-band corrections

The M9HCT-A-SMA is suitable for high-precision applications such as the UAV market, where high performance and low weight are the driving factors in antenna selection.

The active helix design features Maxtena’s patented, compact and lightweight Helicore technology. This technology offers excellent pattern control, polarization purity and high efficiency in a compact form factor.

The M9HCT-A-SMA is independent of the ground plane and offers extremely low power consumption and minimal phase center variation across the azimuth for high-precision applications. The antenna offers an excellent axial relationship and ensures that multipath errors are mitigated.

For the embedded version, Maxtena offers support in installing and integrating the embedded antenna to provide exceptional antenna performance. Maxtena can embed the antenna in any case and then customize the antenna to suit the materials, electronics, and space of the case

“The M9HCT-A-SMA combines all of the lower and upper GNSS bands including L1 / L2 / L5 across all constellations and provides L-band corrections,” said Vanja Maric, Maxtena’s chief commercial officer. “At the same time, this antenna is the smallest solution with such a performance on the market. The excellent axial ratio and multipath rejection allow the antenna to operate in the most RF noise environments. We are seeing a trend towards higher accuracy demand in various industries, from autonomous vehicles and robotics to commercial products such as lawn mowers and robotics that use our antenna solution. “
