Sinuous Antennas

Sinuous Antennas

COTS and custom designed Dual Linear and Dual Circular Polarised, sinuous antennas for direction finding, ELINT, RWR and ESM airborne, sea and ground based applications.

The Steatite family of sinuous antennas simultaneously handle signals of any two orthogonal linear polarisations and simultaneous left and right handed circular polarisations dependent on antenna design. This provides intercept opportunities for a wide range of arbitrarily polarised signals, from devices also giving a wide bandwidth and broad beamwidth. The sinuous antennas can also be used as feeds for reflector antennas where they give the advantage of a stable phase centre across the frequency band. As with other Steatite products, bespoke designs or modifications may be accommodated.
