  abstract =     "Whereas the current practise of designing antennas by
                 hand is severely limited because it is both time and
                 labour intensive and requires a significant amount of
                 domain knowledge, evolutionary algorithms can be used
                 to search the design space and automatically find novel
                 antenna designs that are more effective than would
                 otherwise be developed. Here we present our work in
                 using evolutionary algorithms to automatically design
                 an X-band antenna for NASA's Space Technology 5 (ST5)
                 spacecraft. Two evolutionary algorithms were used: the
                 first uses a vector of real-valued parameters and the
                 second uses a tree-structured generative representation
                 for constructing the antenna. The highest-performance
                 antennas from both algorithms were fabricated and
                 tested and both outperformed a hand-designed antenna
                 produced by the antenna contractor for the mission.
                 Subsequent changes to the spacecraft orbit resulted in
                 a change in requirements for the spacecraft antenna. By
                 adjusting our fitness function we were able to rapidly
                 evolve a new set of antennas for this mission in less
                 than a month. One of these new antenna designs was
                 built, tested, and approved for deployment on the three
                 ST5 spacecraft, which were successfully launched into
                 space on 22 March 2006. This evolved antenna design is
                 the first computer-evolved antenna to be deployed for
                 any application and is the first computer-evolved
                 hardware in space.",
