Abstract

We describe millimeter-wave near-field measurements made with the new National Institute of Standards and Technology (NIST) robotic scanning system. This system is designed for high-frequency performance, is capable of scanning in multiple configurations, and is able to track measurement geometry at every point in a scan. We have measured a WR-5 standard gain horn at 183 GHz using the spherical near-field method. We compare these results to a theoretical model and to a direct far-field measurement.
