Abstract
An antenna and its associated components are consolidated in a small measurement box, and multiple tests are competed simultaneously, with a single vector network analyzer. This can be done by treating the 'Far Field' measurements (typically measured on antenna/RCS ranges) as another port of a larger passive network. After characterization of one ideal 'gold' unit (or a sample set of “gold” units), the S-parameters of subsequent units are measured in the same passive test box environment. The results of these subsequent tests are compared to the results of the “gold unit's” test, and if they are repeated to within some tolerance, electrical similarity can be proven.
