A Hierarchical Optimization Procedure for CAD of Antenna Waveguide Components

Modern CAD tools for antenna waveguide components design require the introduction of optimization strategies in order to reduce both the computer effort and the overall complexity of the optimization task. We introduce a hierarchical optimization procedure which breaks down the overall problem in a sequence of simpler tasks, hence also reducing the parameter space dimensions and avoiding local minima traps. Examples of manufactured components illustrate the methodology and confirm the quality of the electrical performances obtained via the suggested optimization procedure.
