"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 optimisation loop may be employed in order to reduce the fundamental mode resonant frequency. This is accomplished with the valInFEM, PSOoptimizer and IFSLimiter applications. Theory of characteristic modes is then used to refine the results and finally antenna is simulated with full-wave CST simulator, built and measured."@en .
