      A compact low-profile high-impedance surface for use as an antenna ground plane 

      Raza, S.; Antoniades, Marcos A.; Eleftheriades, G. V. (2011)
      A compact and low-profile high-impedance surface is proposed which offers a significantly smaller footprint without affecting the usable reflection phase bandwidth of the structure. The unit cell of the proposed surface ...

      Compact, wideband and multiband antennas based on metamaterial concepts 

      Antoniades, Marcos A.; Zhu, J.; Selvanayagam, M.; Eleftheriades, G. V. (2010)
      In this review article, various antenna designs that are based on metamaterial concepts are presented which have been developed at the University of Toronto. Specifically, several antennas that are based on the zero-index ...

      A folded-monopole model for electrically small NRI-TL metamaterial antennas 

      Antoniades, Marcos A.; Eleftheriades, G. V. (2008)
      An improved model for analyzing electrically small NRI-TL antennas is proposed, that highlights the methods that enable these antennas to offer a good impedance match and a high radiation efficiency compared to previously ...

      A multi-band NRI-TL metamaterial-loaded bow-tie antenna 

      Antoniades, Marcos A.; Eleftheriades, G. V. (2011)
      A compact, fully-printed and low-profile bow-tie antenna is proposed, which exhibits multi-band performance by loading a reference bow-tie antenna with series capacitive gaps and shunt inductive strips, to form an asymmetric ...

      Multiband compact printed dipole antennas using NRI-TL metamaterial loading 

      Antoniades, Marcos A.; Eleftheriades, G. V. (2012)
      A compact, fully-printed negative-refractive-index transmission-line (NRI-TL) metamaterial-loaded dipole antenna is proposed, which exhibits multiband resonant characteristics that are not harmonically related. The multiband ...

      A NRI-TL metamaterial-loaded bow-tie antenna 

      Antoniades, Marcos A.; Eleftheriades, G. V. (2011)
      A fully-printed and low-profile bow-tie antenna is proposed, which exhibits multi-band performance by loading a bow-tie antenna with series capacitive gaps and shunt inductive strips, to form an asymmetric two unit-cell ...

      A zero beam-squinting leaky-wave antenna using NRI-TL metamaterials 

      Kossifos, K. M.; Antoniades, Marcos A. (Institute of Electrical and Electronics Engineers Inc., 2015)
      A planar zero beam-squinting leaky-wave antenna is proposed at 5 GHz, consisting of a periodic arrangement of negative-refractive-index transmission-line (NRI-TL) metamaterial unit cells. The antenna is centre-fed through ...
