Abstract
On the basis of far field pattern distributions, a robust analytical approach for the determination of the Q value -linked to the classical concept of superdirectivity- has been developed. Circular Taylor distributions were used for showing the performance of the method in high efficiency distributions. In this sense, a minimization of this Q value is interesting for avoiding power losses in the invisible region of the pattern. Accordingly, several numerical optimizations were performed and results of improving this Q -by allowing different relaxation levels in the requirements in efficiency- have been developed and their results are here discussed.File | Dimensione | Formato | |
