    • A Simple Ultra-Wideband Suspended Stripline Bandpass Filter With Very Wide Stop-Band 

      Autor: Balalem, Atallah; Menzel, Wolfgang; Macháč, Jan; Omar, Abbas
      (IEEE, 2008-03)
      This letter introduces a simple ultra-wideband suspended stripline filter with a pass-band from 3.1 to 10.6 GHz and a very wide stop-band up to more than 25 GHz. The filter is realized by capacitive coupling of a quasi-lumped ...

    • Quasi-Elliptic Microstrip Low-Pass Filters Using an Interdigital DGS Slot 

      Autor: Balalem, Atallah; Ali, Ali R.; Macháč, Jan; Omar, Abbas
      (IEEE, 2007-08)
      This letter introduces a DGS slot with an interdigital shape. The resonant frequency of the slot can be easily controlled by changing the length of the metal fingers, without changing the area taken by the structure. Using ...
