| Abstract: | This paper analyses the filtering characteristic of an open-circuit edge parallel coupled microstrip band-pass filter,and then the filter is simulated by ADS.The filter’s schematic can be optimized many times in ADS.Parameters need be optimized one by one,which make the optimization’s speed more fast .A band-pass filter with the center frequency of 3.05GHz and bandwidth of 3.3% is optimized,whose conclusion meet the design index well.Several problems in conventional design means can be solved by ADS.Such as,coupled microstrip filter’s bandwidth departure the target’s easily,lose too much in the band-pass area,need too many experiments and waste lots of raw materials. |
