Macháč J.: Microstrip Line on an Artificial Dielectric Substrate, IEEE Microwave and Wireless Components Letters, Vol. 16, No. 7, pp. 416-418, July 2006.
This letter presents a new version of an artificial dielectric substrate and a microstrip line built on top of this substrate. The substrate is fabricated as a two-dimensional array of metallic posts separated from the top conductor by a thin dielectric slab. This structure can show a very high effective permittivity and can therefore offer a substantial reduction in the dimensions of microwave circuit elements.
