In this paper, we are proposing a design of a spur line single and dual band bandstop filter. We designed, fabricated and characterized spurline filters in two notch frequencies, one at 3.25GHz and the other at 5.25GHz. The designed filters simulated using Keysight Technologies ADS software and fabricated on FR-4 substrates shows S11 of 1dB and S21 of 20 dB at notch frequency 3.165GHz and S11 of 2dB and S21 of 21dB at notch frequency 4.98 GHz. These two spurlines were combined to obtain dual band band stop filter resulting in S11 of 2dB and S21 of 25dB at notch frequency 3.038 GHz and S11 of 3db and S21 of 26dB at notch frequency 5.2GHz.
