A simple Ultra-Wideband filter with Notch band using SIR and Three parallel lines

In this paper, A simple Ultra-Wide band filter with Notch bang using SIR and Three parallel lines is presented. Input and output ports are parallel three lines for signal transmission. DGS (Defected Ground Structure) is well suited for the design SoP microwave passive components and interconnect in the new microwave integrated technology. In order to increase the coupling strength of the signal in three parallel lines at the input and output structures, DGS is used. We used this structure to achieve the design of ultra-wide band filter in the 3.1 GHz to 10.6 GHz range, and to achieve the inhibition of 22.18 dB at 6.25 GHz.
