A family of eight
antennas covering the frequency range 0.4 –
18 GHz is capable of reaching ultra-high
field strengths in the near field, that is
not attainable using traditional systems.
Steatite uses antenna
arrays, lenses and extended gain antennas to
achieve this performance.
Steatite HiRF antennas
are able to focus RF energy at short
distances from the aperture.
3 kV / m at one meter can
be achieved in free field tests with 3 dB
spot sizes 150mm or greater.
Focusing is achieved by
using dielectric lenses or by dividing the
aperture up into four co-phased smaller horn
Various mounting options
are available ranging from fixed-mount to
As with other Steatite
products, bespoke designs or modifications
may be accommodated.
