Efficient Antenna Scan Response Models for Large Phased Arrays

Global surrogate models are presented for antenna elements in large phased arrays, to cheaply and accurately model scan-dependent impedance and radiation responses for systems with wide-angle scanning requirements. Adaptive sampling combined with rational and Kriging interpolation is found to produce accurate, convergent models within 50 full-wave EM simulations of a patch element within a planar PBC unit cell.
