A Comparison of Fitting Methods for Modeling the Front Door Coupling of Two Nearby Parabolic Antennas

In this article, we present the modeling of the front door coupling of two nearby antennas through different fitting methods. The antennas were considered as a two port network and its coupling was represented by the S21 parameter, which was obtained for diverse configurations by simulation means. The results of different fitting methods were analyzed and compared for different antennas configurations in order to determine the best fitting algorithm.
