How to add RLC components to planar structure in Ansoft Designer

Hi everyone,
I'm simulating PBG structure in Ansoft designer and want to add RLC components to the PBG. First I simulated RLC circuit in ADS and exported touchstone file (s2p), then in Ansoft Designer 6 I created Nport model and imported s2p file. I've been trying to add a 2port model to planar structure but I could not I attached the structure to shoe more clear where I want to add a component. I wonder if anyone could explain me how to add model or RLC component to the middle of the PBG structure.

Any help would be very much appreciated.

Thank you!
