FRACTALCOMS PROJECT: MESHING FRACTAL GEOMETRIES WITH GiD

Antennas based on fractal structures present some particular properties as selfsimilarity and miniaturization that overcome some of the main limitations of classical antennas. Defining and meshing the fractal geometry are the two first stages in the numerical analysis of their electromagnetic behavior. Fractal structures are highly convoluted with very small details, nevertheless, some of these fractals can be easily defined with very few parameters using the concept of an iterated function system (IFS). Some other important points about the meshing of fractal geometries are also described in this communication. GiD provides a very suitable environment to create arbitrary 3D meshes. One of the objectives of Fractalcoms project is to extend the capabilities of GiD in order to generate automatically the mesh of fractal geometries taking as input data the IFS parameters.
