Research Article Joint use of Bond Graph Approach and Scattering Formalism for an Electrical Modeling of Patch Antenna Array

In this study we present another joint application of the bond graph approach and the scattering formalism for an electrical modeling of a patch antenna array. First, the aim of our application is to build the overall bond graph model of the antenna array using the first principle (physical interpretation to bond graph word of a physical system) of the developed technique by our research team. Second, the simplified model, performed on the found conventional bond graph model gives us easily, on the one hand, the scattering matrix S ij (applying the analytical operating procedure); on the other hand, the electrical model of the patch antenna array. The proposed technique is validated by a comparative study between the simulations of the scattering parameters S ij of the studied structure and the simulations of those founded directly from the electrical model of the antenna. In this study we recall that, the used networks patch antenna has multi triangular and geometric structures.
