Abstract
An innovative antenna design technique, based on evolutionary programming, has been devised and applied to the design of broadband parasitic wire arrays for VHF-UHF bands with a significant gain. The chosen fitness function includes far-field requirements, as well as wideband input matching specifications. The latter requirements, which must be present in every useful antenna design, allow to stabilize the algorithm, and to design both optimal and robust antennas. The designed antennas show significant improvements over existing solutions (Yagi and LPDA) for the same frequency bands.
