Lumped Port Assignment on Substrate Surface in Ansys HFSS

Hello,

I am trying to do a Ansys hfss and Ansys circuit cosimulation using dynamic link. However, i am facing some problem in defining lumped ports on top of substrate surface. Any suggestion, how can I do this. I have tried to make integration line but the output is not making any sense to me.
Below picture should give overall idea of the structure I am trying. Thanks
