M.S. Shkurkin Al’manac of Modern Metrology № 2 (7) 2016, pages 85–89 The article presents the main practical aspects that allow the radiation characteristics of antennas to be effectively recovered from the results of measurements of the amplitude-phase distribution of the tangential components of the electromagnetic field on a spherical surface in the near field. … Continue reading A fast transform algorithm in recovering the directivity characteristics of antennas from the results of measurements on a spherical surface in the near field
