Abstract

A very efficient low profile leaky-wave antenna (LWA) made of high aspect ratio (HAR) electromagnetic bandgap (EBG) unit cells is proposed. The idea is the first attempt to incorporate HAR EBG cells into the structure of LWAs. To develop the idea, a LW transmission line (LW TL) textured of HAR EBG cells is introduced, and then an open circuit piece of such a LW TL is utilized as a LWA. The results show that the simultaneous contribution of EBG cells and HAR metal traces yields maintained efficiency while reducing the structure resonance.
