Hello Everyone!!
I have designed a SIW BPF using/etching koch fractal. I am getting good response with high selectivity. what can be the explanation of this?? Also second iteration has better selectivity..why??
Does second iteration introduces more L & C than first iteration?? Is selectivity depend on values of L & C..If so, is there any relationship between them..
Also one last query, SIW is high pass filter..but when we cut a slot on it, it become Band pass...what is the mechanism of this..How does the slot behaves and why it causes change in its behaviour??
kindly share your knowldge!!!
ThanksRegards
