A powerful iterative method is presented for the synthesis of arbitrary reconfigurable antenna arrays. The algorithm yields very good results also for arrays consisting of a large number of elements. The reconfigurability is achieved by phase-only control. The excitation amplitudes may be different for different array elements, and are not preassigned, but are optimized. Furthermore, the electric field vanishes in a number of prescribed points located in the near-field region, so that a strong field reduction is obtained in a neighborhood of them.

Abstract
A powerful iterative method is presented for the synthesis of arbitrary reconfigurable antenna arrays. The algorithm yields very good results also for arrays consisting of a large number of elements. The reconfigurability is achieved by phase-only control. The excitation amplitudes may be different for different array elements, and are not preassigned, but are optimized. Furthermore, the electric field vanishes in a number of prescribed points located in the near-field region, so that a strong field reduction is obtained in a neighborhood of them.File in questo prodotto:
