A novel method of using bypass coupling SICC resonator to generate transmission zeros in filter stopband to improve stopband attenuation is presented. A SIW quasi-elliptic function filter for Satellite Communication application with bypass coupling SICC resonator is designed and fabricated to validate the method. The results show that the method is effective on improving the filter stopband performance.
