چکیده
|
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.
