Abstract
A technique of synthesis of near-field (NF) amplitude and phase patterns of linear, planar, or volume arrays of finite size, or of arrays located on a planar contour of finite size, is presented. The array could consist of point dipoles or directive elements. The criterion for prescribing the NF (amplitude and phase) pattern information in the synthesis problem for unique determination of array excitation currents is also stated. The proposed near-field synthesis technique is based on the potential integral solution of source currents, Nyquist sampling of the near-field data, and the technique of linear least-square approximation (LLSA). The NF pattern synthesis technique is illustrated to synthesize a variety of NF patterns with a number of array configurations.
