The Nearfield testing method is now recognised as the first choice for an Antenna Measurement System. There are 18 such systems from Nearfield Systems Inc (NSI) installed in the UK ranging from the smallest 1mx1m Planar Scanner to a 7m high Cylindrical Scanner and include Spherical scanners at some of the world’s leading antenna manufacturing companies. NSI’s systems are used in many Universities in the UK and Ireland and their software and support is recognised with over 450 systems worldwide. They are the world leaders in this technology and have also expanded their expertise into Far field systems.

Near-field Antenna Measurement techniques were first developed to improve and increase antenna testing accuracy with the satellite industry being instrumental in its development. Increased testing throughput, lower testing cost, excellent antenna diagnostics and masses of data such as antenna pattern and gain information, provided NSI users with all of the benefits lacking from traditional Far-field sites. NSI continue to push the boundaries of technology with their pioneering MARS software and developing systems that measure antennas at frequencies greater than 650GHz.

Frequensys personnel have been involved in the installation and commissioning of Nearfield systems. Together with Siepel, who provide anechoic chambers for NSI in other parts of Europe, Frequensys can provide full Antenna Measurement solutions and provide our customers with the peace of mind of a fully operational system.
