  abstract =     "In the last decade the study of frequency selective
                 surfaces (FSS), i.e. periodic metal patches printed on
                 a dielectric substrate, has regained interest both in
                 the microwave and millimeter-wave region, with the
                 introduction of electromagnetic band gap (EBG)
                 materials. This entirely new class of structures,
                 encompassing FSS as one of its subclasses (planar EBG),
                 were named in analogy to the band gaps present in
                 electric crystals and present some very interesting new
                 electromagnetic properties. By choosing the proper
                 geometry of the periodic surface we can shape the
                 electromagnetic behaviour of EBGs structures in order
                 to prevent the propagation of electromagnetic waves in
                 a given frequency band. In particular, EBG surfaces can
                 be made to act as artificial magnetic conductors (AMC)
                 ground planes, showing a reflection coefficient with
                 magnitude 1 and phase 0. The ultimate goal is then to
                 design and incorporate such metamaterial-substrates in
                 antenna structures in order to improve antenna
                 performance. Currently there is a growing interest in
                 antennas integrated with an EBG surface for
                 communication system applications, covering the 2.45
                 GHz and the 5 GHz wireless networking bands. The main
                 drawback of this strategy is the reduced bandwidth of
                 the complete antenna, since the frequency range over
                 which these EBG surfaces behave as an AMC is usually
                 narrowband and fixed by their geometrical
                 configuration. For this reason we focused our research
                 both on the optimisation of EBGs and the synthesis of
                 new promising geometries using genetic programming
