"This paper presents a possible application of an artificial dielectric substrate. The substrate is fabricated as a 2D array of metallic posts separated from the top conductor by a thin dielectric slab. The effective permittivity of a microstrip line fabricated on this substrate depends on the dimensions of the posts, the permittivity of a dielectric material filling the space between the posts, and on the thickness and permittivity of the top dielectric slab. Due to the high effective permittivity, a substantial reduction in the dimensions of the microwave circuit elements is possible. Two 3 dB branch line couplers were designed, fabricated and measured by applying the microstrip line on this artificial dielectric substrate." . . . . . "4"^^ . "3"^^ .
