Efficient yield estimation of multiband patch antennas by polynomial chaos‐based Kriging

Yield estimation of antenna systems is important to check their robustness with respect to the uncertain sources. Since direct Monte Carlo sampling of accurate physics‐based models can be computationally intensive, this work proposes the use of the polynomial chaos–Kriging (PC‐Kriging) metamodeling method for fast yield estimation of multiband patch antennas. PC‐Kriging integrates the polynomial chaos expansion (PCE) as the trend function of...
