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 to -37dB in 2.6GHz-3.4GHz.
