An Improved Antenna Gain Extrapolation Measurement



Jason Coder, David R. Novotny, Jeffrey R. Guerrieri, Michael H. Francis, Brian C. Stillwell


An improved antenna gain extrapolation measurement is proposed. The improved method consists of a vector network analyzer, a pair of RF optical links, and a pair of waveguide mixers. We present a detailed description of the new extrapolation measurement setup, discuss the advantages and disadvantages, and validate the new setup by measuring the gain of an antenna previously measured with a traditional extrapolation setup. After presenting the comparison, we will discuss applications of this measurement system that extend beyond extrapolation gain measurements (e.g., spherical near- and far-field pattern measurements).
