Spiral Antennas

Spiral Antennas

COTS and custom designed cavity-backed spiral antennas cover the frequency range from 0.5 to 42 GHz and provide wideband performance with left or right hand circular polarisation.

Steatite spiral antennas provide broad beamwidth with low squint, smooth radiation patterns and purity of circular polarisation. Typical airborne and ground based applications include 360° direction finding, spectrum management, RWR and ESM. The Company provides custom designed spiral antennas and if required, integrate lensed radomes to improve performance.
