From: High-efficacy global optimization of antenna structures by means of simplex-based predictors

Selected Antenna I responses for the designs rendered by the developed globalized simplex-based optimization algorithm: (a) design 1, (b) design 2, (c) design 3. Antenna response for the initial design x(0) (produced by the global search stage) is shown using dashed line. Antenna response for the final design is shown by solid line. The intended centre frequencies (i.e., 2.45 and 5.3 GHz) are shown using vertical lines.
