UWB Array Design Using Variable Zo Technology and Central Force Optimization

This note applies Variable 0 Z technology to the design of an Ultra Wideband (UWB) YagiUda array optimized using Central Force Optimization. Variable 0 Z is a novel and proprietary approach to antenna design and optimization that treats the feed system characteristic impedance, 0 Z , as a design variable instead of a fixed design parameter as is traditionally done. Variable 0 Z is applicable to any antenna design or optimization methodology, and using it will generally produce better antenna designs across any user-specified set of performance objectives.
