2GHz Microstrip Low Pass Filter Design with Open-Circuited Stub
Journal Title: IOSR Journal of Electronics and Communication Engineering(IOSR-JECE) - Year 2018, Vol 13, Issue 2
Abstract
A 3 pole 2GHz Butterworth microstrip low pass filter is designed and fabricated based on the Opencircuited stub microstrip realization technique. The filter is designed using the FR4 substrate and the performance of the design is simulated using the ADS EM simulation tool. A comparison of the fabricated Open-circuited stub filter’s performance with the ADS simulation showed a marginal average deviation of less than 5%. At the cut-off frequency of 2GHz, the Open circuited stub filter produced an insertion loss of -3.009dB, while the stop-band characteristics exhibited an attenuation of -19.359dB at the stop-band frequency of 4GHz and a peak attenuation up to -35dB at 4.5GHz.
