parallel-coupled stripline

Hi
I am simulating a parallel coupled bandpass filter with stripline structure in ADS2004A, but I can't find parallel coupled stripline with only 2 ports for the filter design.
The picture has been attached .
So, How can I realize the component of the parallel coupled stripline with TLines-Stripline in Schematic?

Thanks in advance!

I think you can use an SLEF (Stripline Open-End Effect)
with negligible length respect to SCLIN.

check this , it may be a solution as well

u can make em simulation for it in momentum and import it as ablack box in ADS and use it for ur purpose it will b accurate

khouly,Your model likes being built in Microstrip line? if the figure attached is the equivalent circuit of the parallel coupled stripline with opposite port in different strip?
 

try built like it with strip lines , not microstrips

u can use and em simulator model the stripline geometry in that and analyse over desired frequwncy..u will get the S-Parametr file..this file u can import in ADS use it as a component defined by you analyse ur filter geometry
