On the deterministic synthesis of aperiodic ring antenna arrays

A deterministic approach to the synthesis of aperiodic ring antenna arrays with uniform-amplitude excitation is presented and thoroughly discussed in this paper. The proposed technique, based on the auxiliary array pattern concept, is aimed at the deterministic determination of the optimal array element density and phase tapering useful to mimic a desired radiation pattern. In particular, the developed antenna placement method does not require any optimization procedure, resulting in a dramatic reduction of the antenna design times.
