      Arbitrary length zero-phase substrate integrated coaxial lines using NRI-TL metamaterials 

      Quddious, A.; Nikolaou, S.; Antoniades, Marcos A. (Institute of Electrical and Electronics Engineers Inc., 2017)
      Arbitrary-length zero-degree phase-shifting lines are presented at X-band that are based on negative-refractive-index transmission-line (NRI-TL) metamaterials implemented in substrate integrated coaxial line (SICL) technology. ...

      A multiband monopole antenna using a double-tuned Wheeler matching network 

      Antoniades, Marcos A.; Eleftheriades, G. V. (2010)
      A double-tuned matching network is proposed, which replaces one of the resonant circuits in aWheeler matching network with a λg/2 transmission line in order to achieve broadband and multiband matching performance. The ...
