Cobham Intros Ultra Wideband, Dual Polar, Sinuous Spiral Antenna
|
7 August 2013
CHEVELEY, United Kingdom - This newly developed
sinuous, spiral antenna is particularly suitable for security, surveillance
and EW applications. Its rugged, machined housing makes it ideal
for harsh environments.
All
development engineering and manufacture has been carried out in the
UK which means that the product is not subject to ITAR.
Ultra wideband, frequency covers 2 to 18 GHz.
Directional, the Beamwidth is 65° to 95° in azimuth and elevation, with
a maximum Beam Squint of only +/-4 degrees to -3 dB points across
the band. Dual circular (Right and Left Hand)
polarisation over the entire band means that there is no likelihood
of any frequency being missed at any polarisation. The
very good, consistent, monotonic radiation patterns enable Direction
Find (DF) systems to provide accurate Angle of Arrival data when using
amplitude comparison techniques. Amplitude-matched sets of antennas
can be provided. Phase-matched sets of antennas can be
provided, with support radiation pattern data, to allow high resolution
DF. Dimensions 84 mm (3.3”) by 67 mm (2.6”) diameter,
weight 250 grams (8.8 ounces). Model reference
SSA0218RL/2044, Sinuous Spiral Antenna with Dual Circular Polarisation.
