Introduction to antenna measurement and post-processing techniques

All the contents included in this book have had important theoretical and practical developments during the last years. All these methods are based on the translation of the near or far-field data to other domains (as modes or currents on the antenna surfaces). In those domains, the antenna engineers can recognize and correct errors in an easiest and fastest way, having some a priori information of the antenna. Obviously, the progress in this field has been supported by a deep study in universities and research centres. Also, commercial antenna diagnostic tools, as Insight (MVG) or Diatool (TICRA), have been proposed for doing very accurate source reconstructions using integral equation methods. Other commercial tools, as Mars (NSI), Isofilter (MI-Tech) or MVEcho (MVG), use the decomposition of the acquired field in cylindrical or spherical modes to filter out spurious signals.
