Abstract :
A SIW bandstop filter is designed by coupling two cavity resonators to the SIW line. Dual-radial cavity resonators are proposed to design the SIW bandstop filter. Two single radial cavity resonator SIW bandstop filter are designed first. After that, a dual-radial cavity resonator SIW bandstop filter is designed based on the two single radial cavity resonator SIW bandstop filter. The designed bandstop filter operates at X-band frequency with a stopband from 8.7GHz to 9.2GHz, and it is implemented on RO4350B substrate with a thickness of 0.508mm. An insertion loss of less than 3dB is achieved, and the bandstop filter have a sharp roll of with attenuation of -34dB. This bandstop filter can be applied in the radar system.
