Recent advances on metamaterials with applications in terminal and high gain antennas

This paper presents recent advances in the design and applications of metamaterials: Electromagnetic Band Gap, Artificial Magnetic Conductor and LH surfaces. Miniaturised EBG surfaces are studied and implemented using closely-coupled double-layer topologies. Antenna characteristics are shown from a multifrequency array (using non-uniform Left Handed (LH) superstrate), a planar base station antenna and a compact mobile handset prototype (incorporating a thin flexible miniaturised EBG surface). Frequency de-tuning, efficiency and radiation pattern results are presented.
