Rapid statistical analysis and tolerance-aware design of antennas by response feature surrogates

Fast statistical analysis of antenna structures using response features is addressed. Our approach exploits response surface approximations of suitably selected characteristic points of the antenna response. Taking advantage of close-to-linear dependence of the feature point coordinates on antenna geometry parameters allows for accurate yet cheap yield estimation. Extension of the technique for tolerance-aware design is also discussed. The approach is demonstrated using a dual-band patch antenna.
