Comparison of Optimization Approaches for Designing Nonuniform Helical Antennas

摘要

Comparison of various optimization approaches for the design of nonuniform helical antennas is presented. The considered helices have linearly varying radius and pitch. Results show that this design has many similar (or suboptimal) solutions with significant differences in geometry. Combination of particle swarm optimization and Nelder-Mead simplex algorithm proved to be a robust and an efficient optimization approach.
