摘要: A new band pass narrow band, miniaturized and single resonance within a wide range of frequency selective surface structure loaded with mount capacitors suitable for low narrowband waveguide filter applications is presented. The consists five unit cells in one direction notch square ring elements each two lumped placed on the transverse plane rectangular waveguide. To reduce simulation time design procedure, split-field update FDTD method used analysis cell analogous infinite at different oblique incidence waves to predict FSS performance As an application, has been designed be easy fabricate inexpensive S-band band-pass filter. By using capacitors, several undesirable higher order frequencies near dominant are eliminated dimensions reduced considerably compared without capacitors.
