abstract = "We present a case study showing a human-competitive
design of an evolved antenna that was deployed on a
NASA spacecraft in 2006. We were fortunate to develop
our antennas in parallel with another group using
traditional design methodologies. This allowed us to
demonstrate that our techniques were human-competitive
because our automatically designed antenna could be
directly compared to a human-designed antenna. The
antennas described below were evolved to meet a
challenging set of mission requirements, most notably
the combination of wide beamwidth for a circularly
polarized wave and wide bandwidth. Two evolutionary
algorithms were used in the development process: one
used a genetic algorithm style representation that did
not allow branching in the antenna arms; the second
used a genetic programming style tree-structured
representation that allowed branching in the antenna
arms. The highest performance antennas from both
algorithms were fabricated and tested, and both yielded
very similar performance. Both antennas were comparable
in performance to a hand-designed antenna produced by
the antenna contractor for the mission, and so we
consider them examples of human-competitive performance
by evolutionary algorithms. Our design was approved for
flight, and three copies of it were successfully flown
on NASA's Space Technology 5 mission between March 22
and June 30, 2006. These evolved antennas represent the
first evolved hardware in space and the first evolved
antennas to be deployed.",

notes = "* better coverage * significantly higher efficiency *
fewer parts: lower cost, increased reliability, easier
manufacture * naturally matched to 50 Ohms * faster
design time * rapid redesign accomplished at a small
cost and in a short time frame",
