Near Field Antenna Test Range

The Near Field Antenna Test Range facility offers companies fast and accurate characterisation for a wide variety of antennas. The facility itself is a state-of-the-art Spherical Near-Field Range, housed in a purpose built 4m x 4m x 4m anechoic chamber and operates in the frequency range of 750 MHz to 40 GHz. The Near Field Range is available for daily or monthly lease (subject to availability) and our experts are on hand to support you with each stage of your testing.

-NSI-MI Spherical Near-Field Range measurement system with azimuth (Phi) turntable, Theta over Phi swing arm, and polarisation axis (scan area: 360 degrees in Phi and 270 degrees in Theta).
-Rohde & Schwarz ZNB 40 Vector Network Analyser.
-High precision measurements in the frequency range 700 MHz to 40 GHz.

-Antenna measurement data and analysis include:
-3D complex far-field co-polar and cross-polar radiation patterns (for linear or circular polarisation)
-Axial ratio (over 3D surface)
-Multi-frequency directivity, gain and efficiency
-Phase centre & group delay vs frequency
-Microwave holographic projection to arbitrary measurement planes

We also offer additional industry-leading capabilities for RF testing of satellite communication systems and components including: signal & spectrum analysers; vector network analysers; vector signal generators; channel emulator; programmable step attenuators; and programmable amplitude & phase shifters. The Near Field Range is located inside the Electron Building at Harwell Campus alongside our Compact Antenna Test Range.
