Parametric Macromodeling of the Coupling Between Two Nearby Parabolic Antennas Using the Cauchy Method

In an effort of determining the cross coupling between two nearby parabolic antennas, a parametric modeling of the front door coupling, using Poles and Residues, extracted through the Cauchy method is presented. Different parameters of the system were taken in consideration, among them: distance between antennas (15 m, 45 m, 100 m) antenna diameter (0.6 m, 0.9 m, 1.2 m), among others. A rational model is obtained for each parameter configuration. The resonances extracted of the complex S-parameters data was validated comparing the original signal and its reconstruction (a similarity of 98% in average). These validated resonances describe the behavior of the communication link between antennas, and its movement, when the configuration is changed, expose the interference parameters desired.
