Maxtena is a world leader in the development of wireless communications and RF solutions for terrestrial and satellite-based networks. Our advanced proprietary technologies power high-performance GNSS, SATCOM, LTE and Wi-Fi antennas for unmanned systems operating on land, in the air and at sea, including UAVs (unmanned aerial vehicles), UGVs (unmanned ground vehicles) and USVs (uncrewed surface vessels).

Helicore – advanced GNSS helix antenna technology

Our patented Helicore technology provides a versatile and low-cost platform for rugged GNSS antenna products, optimizing critical design parameters including pattern, polarization purity, efficiency and size. Helicore uses air as the dielectric core, enabling a stable and high-yield manufacturing process and minimizing the typical losses seen in ceramic materials.

GNSS helix antennaHelicore designs integrate active circuitry and filtering into the antenna, and push the limits of axial ratio, bandwidth, and pattern stability. Other key benefits of Helicore technology include:

  • Smaller and lighter compared to ceramic solutions
  • Ground plane-independent designs
  • Excellent axial ratio at lower elevation angles, leading to significant multipath rejection
  • Easily meets 200 V/m and 50 V/m susceptibility requirements

Conformal wave antenna technology

We have combined new advanced materials and a unique dual-feed configuration to create conformal wave antenna solutions that provide a number of advantages over traditional ceramic single- and dual-feed technology.

conformal wave antennasThe novel materials feature the optimum dielectric properties required to achieve the highest bandwidth and greatest efficiency, while minimizing size and weight. These materials also behave like plastics, providing superior versatility during the manufacturing process and making them ideal for challenging embedded GNSS applications with full coverage.

Our conformal wave solutions provide a number of advantages for GNSS applications:

  • Superior axial ratio for full upper hemisphere coverage across all frequencies
  • Stable phase centre variations across all frequencies
  • Superior rejection of cross-polarized signals and multipath components at low elevation angles
  • Excellent L-band corrections performance
