Abstract—Design of an Ultra Wide Band (UWB) filter over 3.1GHz to 10.6GHz using broad side coupled and spur lines in microstrip medium suitable for UWB communications has been presented in this paper. Parameters of broad side coupled lines have been appropriately chosen to achieve ultra wide band response. Spur lines have been incorporated at the input and output feed lines of the filter to imp...

A compact ultra-wideband bandpass filter based on a multilayer printed circuit board (MPCB) structure is proposed in this paper. RO4450F prepreg used to bond three RO4350B dielectric substrates with different thicknesses the MPCB structure. The upper surfaces of are respectively provided copper-coated structures patterns. blind holes and defected ground (DGS) added an filter. Two groups loaded ...
