摘要
Abstract
Against some traditional filters had a poor performances on harmonic suppression and stop-band, a low insertion loss and widened band filter was designed by using improved the traditional stepped impedance resonator (SIR) and combined the defected ground structure (DGS) to increase the stop-band width. HFSS was used to simulating. Results show that the filter has desired performance, in the pass-band, the insertion loss and the return loss are < ldB and >10 dB, respectively, the upper-stop-band frequency is >18 GHz, and the attenuation is >29 dB at 17.5 GHz. The filter can suppress harmonics effectively.关键词
