ADS beginner- Simulating a Tx line

Hello
I am trying to simulate a Tx line (Microstrip Line) on a substrate. I am not new to RF and Microwave Theory but new to ADS.

Here is what I am trying to do -

Simulate a lamda/4 Tx line that is shorted at frequency of 1 GHz on FR4 substrate. I expect to see an open circuit on port 1 since lamda/4 line would transform a short circuit to an open. The schematic is attached. 

Here is the problem:
I am not seeing an open circuit when I observe mag(PortZ(1)) - which is what I expect. I am seeing 50 Ohm 

The line parameters were synthesized using linecalc. What am I doing wrong ? any help appreciated,
