In this article, a design of both high-selectivity and compact one-dimensional electromagnetic band-gap (1D-EBG) cavities is presented, considering the effect of the layers' thickness and of the permittivity of the constitutive materials. Compact and high-selectivity cavities are proposed, to be employed as spatial filters. In particular, EBG antennas can be obtained when the ground plane of a patch antenna is placed in the symmetry plane of these cavities. An effect of enlargement of the equivalent-aperture area is determined, resulting in high-gain radiation. © 2009 Wiley Periodicals, Inc.

Abstract
In this article, a design of both high-selectivity and compact one-dimensional electromagnetic band-gap (1D-EBG) cavities is presented, considering the effect of the layers' thickness and of the permittivity of the constitutive materials. Compact and high-selectivity cavities are proposed, to be employed as spatial filters. In particular, EBG antennas can be obtained when the ground plane of a patch antenna is placed in the symmetry plane of these cavities. An effect of enlargement of the equivalent-aperture area is determined, resulting in high-gain radiation. © 2009 Wiley Periodicals, Inc.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
