%X The design of a patch antenna working in E5 - L1 Galileo, 2.5 GHz and 3.5 GHz bands is discussed. Starting from a classical rectangular patch antenna with four resonant modes located around the required spectrum regions, the tuning of the operating frequencies is obtained by perturbing the perimeter of the antenna shape according to a pre-fractal Koch-like erosion process. In order to show the effectiveness and reliability of the synthesized structure, a selected set of numerical and experimental results are reported and discussed.
