Mathematical Model of a Two-Element Microstrip Radiating Structure with a Chiral Metamaterial Substrate

—A mathematical model of a two-element array is presented, the substrate of which is made of a chiral metamaterial. The method of singular integral representation of a field is used to obtain a system of integral equations for the unknown distribution functions of the surface current densities of the array emitters. The results of calculating the current functions are given, as well as the dependence of isolation between the emitters on the chirality parameter.
