Impedance Characteristics of a Two-Element Antenna Array with a Chiral Substrate

详细

In this paper, we calculated the impedance characteristics of a two-element antenna array with a chiral metamaterial substrate. A system of singular integral equations with Cauchy-type singularity with respect to the unknown longitudinal distributions of the surface current density is obtained. The input impedance dependences on the normalized arm length for various substrate types, as well as various values of the chirality parameter of the substrate, are presented.
