Structure-Based Evolutionary Programming Design of Broadband Wire Antennas

Free registration required

Executive Summary

A design technique for wire antennas, based on the Structure-Based Evolutionary Programming, is used to design a broadband antenna with an end-fire radiation pattern and a very simple geometry, operating in the 3 - 16 GHz frequency band, namely, from the S band to the Ku band. The antenna has been analyzed with NEC-2 during the evolutionary process, looking for high gain, good input match, and robustness with respect to realization tolerances. The outcome of the authors' design procedure shows a very good performance.
