| Abstract: | Based on the requirement for filter's miniaturization in RFID,the filtering characteristic of an compact interdigital microstrip band-pass filter is analyzed in theory,and then simulated by ADS.Parameters need to be optimized one by one,which make the optimization's speed more fast.A band-pass filter with the center frequency of 2.45 GHz and bandwidth of 9% is optimized,and the results meet the design index well.It has the advantages to decrease the testing experiment time,to cut back on the processing cycl... |
