title = "Surrogate-Model-Aided Optimization of the Bandwidth for a Planar UWB Inverted-F Antenna",
abstract = "A new efficient methodology to speed up the optimization of the bandwidth of antenna designs is proposed in this paper. First, the reflection coefficient S11(f) of the considered antenna is compactly represented by Fourier series. Second, the coefficients of the Fourier series are modeled by using the Least-Angle-Regression-Sampling-based Polynomial Chaos Expansion (LARS-PCE). Lastly, the derived surrogate model serves as an extremely efficient engine which can substitute the time-consuming full-wave simulators for the optima seeking. The proposed methodology has been validated on a planar Ultra-Wideband (UWB) Inverted-F Antenna (IFA), whose impedance bandwidth has been increased by more than 18 \% compared to the original design and the computational cost is limited.",
