Fractal antenna engineering concepts have been successfully combined with g
enetic algorithms to develop a powerful design optimisation tool. The genet
ic optimisation approach developed can simultaneously optimise the geometry
of a fractal antenna, locations of loads, component values of loads, and p
rojected length of the fractal antenna. The results suggest that a 30 to 55
% size reduction can be achieved by optimising the fractalisation of a give
n antenna. The knowledge gained from this study is directly applicable to t
he design of miniature multiband fractal antennas.
