Gain Estimation for Electrically Small Antennas with the Use of the Near-Field Zone Measurements

Abstract

a method of the gain estimation based on the near-field measurements is presented. The described method is based on the measurement of the transmission coefficient between two identical antennas separated by the distance that is much less than the wavelength. Comparison of the theoretical and experimental data for ferrite-rod antennas proves that introduced methodology can be used for the gain estimation.
