Abstract :
The validation of the method based on FFT and time-gating to eliminate multipath contributions in antenna measurement has been extended to different types of antennas and tested in different reverberant scenarios, and some representative results have been shown. The achievable accuracy, quantified through the initial and the recovery errors, is highly satisfactory.
