بهینه سازی آنتن لخت شده توسط الگوریتم نقشه برداری چند منظوره با روش لحظات

We propose a new method of manifold mapping optimization method for the lump-loaded antennas to obtain a miniaturization. The surrogate model can be constructed using explicit formulas during optimization iterations. The coarse and fine models of manifold mapping method are evaluated with an adaptive precision method of moments (MoM) simulator. The computation precision is determined by compression thresholds in the adaptive cross approximation (ACA) for the MoM far coupling evaluations. Numerical optimization of the lump-loaded log-periodic dipole antenna is tested to validate the efficiency of the proposed method.
