Differentiated Meta-PSO Techniques for Antenna Optimization

This paper presents the application of the recently developed Differentiated Meta-PSO Technique to the optimization of a linear array that has to guarantee a defined radiation pattern, with tilted main beam on two different frequency bands. The optimization has been carried out adopting as free parameters the amplitude and the phase of the excitation coefficients and as well as the array element relative positions. Analyses of the optimization technique performances are provided too, with respect to the standard PSO convergence rate.
