Non-uniform 1D antenna array optimal configuration via extremum seeking control

Methods to find the optimum non-uniform onedimensional (1D) antenna array geometry for maximizing directivity are presented. These methods develop a novel objective function to incorporate with the extremum seeking control methods considered. A comparison is performed between the major extremum seeking control approaches for solving the resulting optimization problem: (a) Perturbation-based Extremum Seeking Control (PESC), (b) Numerical Optimizationbased Extremum Seeking Control using Particle Swarm Optimization, to confirm the validity and the effectiveness of the proposed methods.
