Abstract

NIST has developed a multi-purpose test range for performing several types of antenna testing including spherical, cylindrical and planar near-field scanning as well as extrapolation measurements. This range uses a commercial, offthe- shelf, six-axis robot and a laser tracker to accomplish highly accurate positioning that allow scanning up to 220 GHz. Nearfield measurements require positioning accuracies of the order of 0.01 to 0.02 wavelengths. We have evaluated the positioning capability of the robot and performed spherical near-field measurements at 183 GHz. We have performed spherical farfield and extrapolation measurements at 112 – 125 GHz. In addition, position data is acquired continuously using the laser tracker, which allows us to compensate for position error in software. We report on the results of these measurements.
