microstrip interdigital bandpass filter

[MONIKA SSN]

hello everyone,
i m trying to design the 5th order interdigital microstrip bandpass filter in ADS..i don't know how to calculate the dimensional values of resonator and i don't know the exact components for designing the filter.i have used the dimensional values calculated for parallel coupled filter using line calculator.but i didn't get the results..please if anyone knows help me

thanks

"Use Passive Circuit Design Guide" then obtain proper layout then simulate this layout with EM Momentum then if it's necessary go back and optimize your layout.
But first thing first read something about "Planar Filter Structures".There are tons of documentation on the Internet , why don't you seek around it ???
