摘要: The design of planar Ultra Wide Band (UWB) band pass filter using periodic Defected Ground Structure (DGS) is presented. realized with interdigital coupled lines, stepped impedance open stub and slotted DGS. Interdigital lines are used to widen the width filter. Stub provide transmission zeros in upper lower stop where as DGS improves return loss It provides an insertion 0.3 dB a wide from 3.1 – 10.6 GHz. also better 19 dB.
