look-alike component in ADS momentum

Dear All
I want to introduce look-alike component from layout to schematic in ADS. And i want to verify whether this will work well by using a simple case. Unfortunately, i had problem when i did these. Could someone help me to figure out what's my problem or do i misunderstand the meaning of the layout comonent?
The following is what i have done.
1. creat a microstrip line and define its substrate in ADS layout, and define its width to make it a 50ohm microstirp line.
2. convert it to be a look-alike layout compent.
3. insert it to the schematic window
4. add port , term to one edge of the microstrip line and add a lumped inductor to the oher edge which will be connected to the ground
5. set the s-parameter range and do the simulation.
Then i got the S11 and Z11 resutls by using this Co-simulation.
The problem i had here is that when i changed the length of the microstrip line and using the Z11 i got to de-embedding the Load impedance(the inductor's impedance), the load impedance will be different. But the truth is the load impedance shouldn't vary with the transmission line length.
Did i do something wrong here? or the layout component only used for the filter?
I need your help. Thank you very much.
