Abstract
The reflection coefficient (Gamma) of an antenna under test (AUT) was measured from 1-port time domain reflectometry (TDR) measurement. Since the TDR measurement is a 1-port measurement, error can be smaller than 2-port measurement technique. In this paper we provide a review of different methods, which is used in time domain for computing Gamma from measured data. The unwanted reflection in antenna measurements introduce error in desired output, by windowing data we show, it can be limited. Another problem is time domain deconvolution in computing Gamma, here we choose filtering method for solving this problem
