In this article, we present the results of a comparative study of three different types of superstrates used to enhance the directivity of a microstrip patch antenna. The three superstrates are frequency selective surface (FSS) with dipole elements; a dielectric slab; and a double negative (DNG) slab. We find that microstrip antennas (MPAs) covered either by an FSS or a plain dielectric slab superstrate provide higher directivities than that realized by using a DNG superstrate. © 2009 Wiley Periodicals, Inc.
