In this study, a reconstructed continuous current distribution is employed to synthesise circular (one ring) antenna arrays with sparseness characteristics. The authors proposal achieves the reproduction of from an expansion in orthogonal basis, taking desired radiation beam pattern as target function. To obtain characteristics, they density tapering technique that provides excitations and locations for each element. They report three numerical experiments show performance compare it other methods literature.
