In this paper, the design of metamaterial-enhanced antenna arrays is carried out exploiting a quasi-conformal coordinate transformation approach. More specifically, the transformation of a physically linear arrangement into a virtual curved array with a larger size is considered by means of an isotropic inhomogeneous lens comprising non-magnetic materials. The effectiveness of the considered approach for the enhancement of the scanning and beamwidth performance of linear arrangements is preliminarily assessed by means of numerical simulations.

Abstract
In this paper, the design of metamaterial-enhanced antenna arrays is carried out exploiting a quasi-conformal coordinate transformation approach. More specifically, the transformation of a physically linear arrangement into a virtual curved array with a larger size is considered by means of an isotropic inhomogeneous lens comprising non-magnetic materials. The effectiveness of the considered approach for the enhancement of the scanning and beamwidth performance of linear arrangements is preliminarily assessed by means of numerical simulations.File in questo prodotto:
