Antenna II: model-predicted |S11| at the design found by optimizing the proposed metamodel (o), and EM-evaluated characteristic (—) at the same design; model constructed for NB = 800. The designs generated assuming the following specifications (lower and upper operating frequency): (a) f1 = 2.0 GHz, f2 = 4.0 GHz, (b) f1 = 2.5 GHz, f2 = 5.3 GHz, (c) f1 = 3.0 GHz, f2 = 4.8 GHz, (d) f1 = 3.0 GHz, f2 = 6.0 GHz. Vertical lines mark the target operating frequencies.
