planar antennas in QuickWave 3d

I have a simply problem with drawing ports in planar structures with groundplane. I tried to analyse simple radiating planar patch (planar antenna). To feed it I used 50 ohm microstip line. I drawn port perpendicular to XY plane (transmission line port) and I made symulation. Before I started, I had attention "Selected point outside metal". I ignored that because i don't know how draw ports propertly. Results doesn't make any sense. My question is: "how to draw port in simple planar patch antenna feeded by the 50 ohm microstrip line?"

Hi
which software you use in ?If the Hfss and ensemble ,you can draw a segment of microstrip line which width satisfies 50Ohm ,then you could set port to simulate .

I know how to do it using HFSS. I must simulate my structure using Quick Wave 3D v 2.1 - this is my software.
