ANTENNA TEST RANGE IMAGING USING SPHERICAL NEAR-FIELD SCANNING

Abstract

Although the theory is straightforward, practical implementation of spherical near-field scanning for evaluating test chambers presents some significant challenges. Among these are the selection of an appropriate probe and the difficulty in minimizing support-structure blockage. We report on recent NIST efforts to address these difficulties and present our most recent results.
