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.
