Spiral Resonator Bandstop Filter Design with Spurlines

Authors : Bhanu Shrestha

Abstract: In this study, we designed and characterized compact Double Spiral Resonator Bandstop Filter (DSR-BSF) with double spurlines. The double spiral and double spurline were used to enhance its performance with dual mode and to suppress the harmonics respectively. Therefore, the designed DSR-BSF achieves a significantly low insertion loss and wider band rejection characteristics. The operating frequency of the measured DSR-BSF is 3.2 GHz for S-band application with a minimum insertion loss of <42.1 dB and return loss is below 0.03 dB in measurement results. The fractional bandwidth was also achieved approximately 54%. The measurement results have a good agreement with the simulation results. Implementation of such resonator filters in Integrated Passive Device (IPD) technology is also possible due to its compactness. The overall dimension of the developed DS-BSF was 0.95H0.34 λg.
