HiRF Antennas

HiRF Antennas

A family of eight antennas covering the frequency range 0.4 - 18 GHz are capable of reaching ultra-high field strengths in the near field, that are 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 metre can be achieved in free field tests with 3 dB spot sizes 150mm or greater. Focussing is achieved by using dielectric lenses or by dividing the aperture up into four cophased smaller horn antennas. Various mounting options are available ranging from fixed-mount to variable geometry. As with other Steatite products, bespoke designs or modifications may be accommodated.
