    Multiobjective optimization of Fractal Radiating Structures Using Modal Decomposition

  • Original language description

    The paper describes in-house developed software tools for design of microstrip patch fractal antennas. As the fractal geometry is quite complex, IFSMaker application was developed purposedly for an easy maintaining of planar fractal structures. In the next step, we are using cavity model technique for modal analysis of internal fields of the patch. This simplified model is reasonably fast, so that optimization loop may be employed in order to reduce the fundamental mode resonant frequency. Particle swarm optimization is used and the PSOoptimizer tool was created to handle it. Theory of characteristic modes (TCM) is then used to refine the results. The crucial problem of use of TCM in the optimization loop is the proper sorting of characteristic modes.The sorting problem is discussed and new method is presented.
