By assuming pre-fractal geometries as reference structures, the synthesis process is faced with an optimization procedure aimed at suitably tuning the geometrical characteristics of the antenna. In order to preliminary assess the effectiveness and accuracy of the proposed approach, the design of a planar dual-band GPS (1L42,15751=Lf MHz) and ( MHz) antenna is described and discussed.
