This paper proposes the application of SIR resonator in an asymmetric coplanar waveguide transmission line to design a novel asymmetric coplanar waveguide band-stop filter with SIR structure. By the cascading of four SIR resonance units in asymmetric coplanar waveguide transmission line, the insertion loss and bandwidth of the filter are improved effectively. The results show that the filter center frequency is 1.8GHz, the lowest insertion loss is 0.4dB, the relative bandwidth is 33.3%, and the highest rejection is -60dB. The present filter features small volume, low insertion loss, high rejection, wide stop-band, easy fabrication, etc.
