a dielectric, but it would also be preferred to make them with fewer wires, to
avoid unnecessary expense.
These preliminary results, then, seem to hold promise, but much more work
is needed to make these antennas useful. Restrictions probably should be placed
on the structures to ensure they do not violate the assumptions of the simulator
and that they are able to be easily assembled. More work also needs to be done to
discover the types of problems best solved with these structures, and the best pa-
rameters for the GA that optimizes them. However, these antennas show that a
GA can design
