Glide-Symmetric Planar EBG Structure for Mutual Coupling Reduction Between Microstrip Patch Antennas

Abstract

In this paper, a fully planar electromagnetic bandgap (EBG) structure exploiting glide symmetry is proposed for mutual coupling reduction between microstrip patch antennas. The proposed structure is studied in terms of dispersion diagrams and full-wave simulations showing a size reduction as well as an increased level of isolation when compared to its corresponding conventional structure without glide symmetry.
