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...
Radiation characteristics of an open-circuit electromagnetic band-gap (EBG) transmission line are employed to demonstrate a new low-profile antenna with high radiation efficiency. The self-excited EBG resonator antenna (SE-EBG-RA) presented is excited using a simple microstrip line, without requiring a separate probe. Tall metal traces enhance radiation while providing less loss, which results in...
