Abstract

This paper presents a distributed millimetre wave spherical near field antenna measurement system for working in the frequency range of 140 to 220 GHz. Both the mechanical and electrical setup are detailed. The mechanical stability of the measurement system during the acquisition has been identified as one of the key factors that affect the measurement accuracy and a good practice is proposed to address the mechanical instability issue for improved measurement accuracy. Room scattering is another major error source. The spherical mathematical absorber reflection suppression (S-MARS) technique was employed for scattering reduction of antenna pattern measurement up to 220 GHz. The effectiveness of scattering reduction using S-MARS was examined and reported.
