Abstract

This paper describes the fundamental theory of line-source radiation from a dielectric slab with a metal-strip grating. A continuous phased array (CPA) method is applied to treat the analytic and numerical problems of antenna interaction with periodic structures. The strip grating on the dielectric surface may result in surface wave elimination and may also be used to support leaky waves. It is shown that high-efficiency and high-gain antennas may be designed on a dielectric substrate with metal strip gratings.
