Dear I think you cannot make coupling matrix directly from EM Model. you can do it by making circuit model and then find out values of each.

Thanks

Dear Mr Amjad,

Thanks for your kind reply.. Do you have more idea of designing such coupling matrix for band pass filter???Can you explain it more elaborately by referring to an example.. actually i am designing a resonant cavity filter and therefore learning to find coupling matrix, coupling scheme etc (pls find attached a reference paper).. Can you get idea how the values of coupling matrix found/calculated for this paper?

Thanks a lot

Using circuit model based ADS analysis can solve your problem.

Dear Dr Elwi,

Thanks a lot for your kind reply. Sir can you please elaborate on the procedure/steps in ADS to do this.. I have designed the SIW BPF filter in HFSS.. I have heard that we have to export .S2P file to ADS and find the coeficients and coupling parameters.. I can export file to ADS but i do not know about steps to be taken in ADS. if you can just mention the steps or send screen shot of steps, it will be oef immense help to me. Please..please extend and reply or email your kind reply at [email protected].

I will be very grateful to you for your this kind favour.

Thanks and Regard

Nitin
