Abstract :
The computer aided design of an inductive iris filter in waveguide technology is described here using the mode matching method. Direct coupled cavity filters form compact structures. Such a bandpass filter is first designed using an equivalent network theory approach. The mode matching method has been used to analyze discontinuities present in the filter and hence its performance is obtained. Using optimization techniques, the analyzed filter dimension are altered to improve its performance
