Abstract:

According to the discontinuities in rectangular waveguide and double-ridge waveguide,a novel double-ridged self-resonant iris is proposed and its characteristics are analyzed.Double-ridged self-resonant iris is applied in the design of a 6-order waveguide bandpass filter,which has a center frequency of 6.70 GHz,with a relative bandwidth of 20.9% and a return loss up to 20 dB.The filter simulation result shows that its spurious passband appears at twice the center frequency.

Key words: double ridge resonator-iris;bandpass filter;waveguide;wide bandstop
