Abstract

We have performed spherical and extrapolation scans of two antennas at 118 GHz using a commercial 6-axis robot. Unlike spherical scanning, linear extrapolations do not precisely conform to the native circular movement of the individual robot axes. To characterize the quality of the data, we performed dynamic position and orientation characterization of the robotic systems. Using laser tracker feedback, we measure the desired, actual and corrected position of the probe antenna relative to the antenna under test while the probe is moving. We correlated the laser tracker data with the mmWave insertion phase to validate dynamic measurement position results at speeds up to 11 mm/s. We previously demonstrated spherical measurements with this system, we present results for extrapolation measurements which require a more stringent accuracies for pointing that general pattern analysis.
