Radiation of a Circular Arc Source in a Limited Angle for Non-uniform
Conformal antennas lack of general analysis methods of their radiation
properties. For a circumference source, we examine the role of the
angular width of the observation domain both in far and near zone in
determining the set of radiated fields. By an inverse problem approach,
the evaluation of the number of independent pieces of information, i.e.
the number of degrees of freedom (NDF), and the analysis of the
reconstructions of point-like sources allow to introduce optimal array
configurations. The results are relevant to the radiation pattern
synthesis problem and to array diagnostics applications.
