Broadband quadrifilar helix antenna

Helix antennas are known for its good circular polarization that makes it suitable for satellite communications. However, present systems only offer limited bandwidth, often less than 8%.

Our new broadband printed quadrifilar helix antenna (BPQH) is composed of 4 wires printed on a flexible dielectric substrate. This configuration enables the bandwidth to reach 30%, keeping a compact size and offering a pure circular polarization on a very large area.

Covered by a radome, this antenna can be mounted on ships for example.
