Novel W-slot DGS for Band-stop Filter

摘要：

　　A novel W defected ground structure (WDGS) was presented.The structure of WDGS was simple, processing easy and performance excellent.After this unit structure was applied to the design of the band-stop filter, its band-stop characteristic was enhanced efficiently and the dimension was reduced.The effects of the WDGS geometric parameters on frequency and width were analyzed in detail A band-stop filter was built by three cascaded WDGS.The bandwidth of the filter was increased effectively and the attenuation to signals was improved.The results show that the filter rejects signals from-25dB to37dB in 2.6GHz-3AGHz.
