Prediction of the input impedance of two coupled dipole antennas in the echelon form

In this paper, the previously introduced fuzzy modeling method is used to model the input impedance of two coupled dipole antennas in the echelon form. The initial data of two coupled dipole antennas in the parallel and collinear form, which are required for the model, are obtained using the MoM. Then, the knowledge of two coupled dipole antennas in the echelon form is easily predicted based on the knowledge of two coupled dipole antennas in the parallel and collinear form and the concept of spatial membership functions. Also, the problem behavior is well approximated. Comparing the proposed model results with MoM shows an excellent agreement with a vanishingly short execution time comparing with MoM.
