    • Bandpass Filters on a Modified Multilayer Coplanar Line 

      Autor: Balalem, Atallah; Hamad, Ehab K. I.; Macháč, Jan; Omar, Abbas S.
      (IEEE, 2006-06)
      The design of compact multilayer coplanar line bandpass filters is presented. These very compact filters make use of the two sides of the substrate of the modified coplanar line. In addition, a transmission zero has been ...

    • Coplanar Waveguide Transmitting a Left-Handed Wave 

      Autor: Macháč, Jan; Hudlička, Martin; Zehentner, Ján; Spiliotis, Nikolaos G.; Omar, Abbas S.
      (IEEE, 2005-10)
      This paper presents a new version of a coplanar waveguide that transmits a left-handed wave. The equivalent circuit of the line unit cell has been derived from the shape of the layout. The values of its elements were ...

    • Left-Handed Coplanar Waveguide 

      Autor: Macháč, Jan; Hudlička, Martin; Zehentner, Ján; Spiliotis, Nikolaos G.; Omar, Abbas S.
      (IEEE, 2005-06)
      This paper proposes a new version of a left-handed coplanar waveguide. The line has a fully uniplanar structure without vias and lumped elements. The series capacitors are represented by interdigital capacitors and the ...

    • New Bulk Metamaterial 

      Autor: Macháč, Jan; Buchar, Pavel; Zehentner, Ján; Omar, Abbas S.
      (IEEE, 2005-10)
      The design, analysis, fabrication and measurement of a new bulk metamaterial is reported in this paper. The structure of the new medium is made up of left-handed parallel strips. The series capacitors are realized by short ...
