We obtain true far-field results for the full array using Hanwha Phasor’s spherical near-field scanner.
Designed and built in-house, this anechoic chamber is used to characterise the performance of antennas under test in the near-field before processing the data to generate accurate far-field radiation patterns in the lab.
We also measure gain, co- and cross-polar levels, 3dB beamwidth and sidelobe level characteristics.
The frequency range is 10-18 GHz and elevation +/- 100°.
Our spherical near-field scanner is used for R & D today but is being prepared for the production environment, ready to calibrate our arrays in line with customer requirements and for quality control and diagnostics.
