The length of the stub is the most important parameter for which you can calculate the electrical lengths θ = βL and characterize the matching.

Nitin Muchhal

Thanks Dear... Can you recommend some papers which show the calculations for te stub length.. i have read multiple papers (mainly of IEEE MWCL) but no one gave design methodology in detail.. if you know some good papers, kindly share with me.. Thanks a lot

Nitin

Ahmed Moulay

You must calculate your electrical length in relation to your upper and lower cutoff frequency. You can look at Pozar's book in the filters chapter.

Pozar's book is an effective support !
