Abstract

This paper describes unit cell structure of AMC (Artificial Magnetic Conductor) with a multi-layer FSS for miniaturization. Two types of unit cell, “Patch type” and “Grid type” unit cell are treated. Moreover, two types of FSS collocation method for multi-layer structure, “Stacked structure” and “Alternated structure” are considered. As the results of analysis, it is shown that the miniaturization effect is obtained only the case of “Patch type” FSS, and there is polarization dependence of AMC with the multi-layer FSS. It is also shown that the most miniaturization effect for unit cell size is obtained by “Alternated structure” when the layers are displaced just a half of the period of the unit cell, and the miniaturization effect is increased as the number of layers is increased.
