Abstract:
In this paper, a spatial-domain Galerkin's procedure in Method of Moments is applied to analyse a cylindrical-rectangular chirostrop antenna. It is assumed that a single-layer chiral substrate is wrap-fabricated around a conducting core-cylinder and that a perfectly conducting and electrically thin rectangular-cylindrical microstrip patch antenna is mounted on the surface of the chiral substrate. By imposing the boundary conditions on the multiple interfaces and applying the scattering superposition method, a complete expression of dyadic Green's functions (DGFs) has been obtained and the current distribution over the cylindrical rectangular chirostrip antenna has been determined. Various radiation patterns due to such a microstrip antenna in the presence of a chiral substrate are obtained and compared with those in the presence of an achiral substrate, so as to gain physical insight into effects of the chirostrip.
