ENGLISH ABSTRACT: We present a robust method to adaptively construct
parameterized models of the full radiation patterns of antennas
and the associated S-parameters. The method sequentially selects
points (geometric parameters of the antenna and frequency)
such that an accurate model is obtained over a constrained
multivariate parameter space. The algorithm consists of a balance
between exploration and exploitation of the parameter space,
resulting in a near optimal coverage of the design space, with
some emphasis being placed in regions of the parameter space
where the patterns or S-parameters vary rapidly. In addition, the
technique is equipped with a measure of absolute error control.
The proposed method is validated through pertinent numerical
examples.
