Antenna measurement using S-parameters

Abstract

Three-antenna extrapolation technique is used for best measurement uncertainty in antenna gain and polarization measurements. In the extrapolation technique, far-field antenna properties can be calculated from a polynomial for curve-fitting the data removed the effect of multiple reflections between transmitting and receiving antennas measured at a reduced distance. This paper proposes a method using S-parameters for reducing multiple reflections between transmitting and receiving antennas.
