| Abstract: |
| This paper discusses a method how to improve the stripline low-pass filter when its performances are decreaced because the width of the conductive strips are changed after the process. The sensitivity of the structure and electrical parameter of the filter is analysed with the EESOF software of HP company, and it is taken as the basis to improve the performances of the filter.The experiments have proved that the performances of the improved filter is clearly increased and stable. |
