Symbol element to simulate patch (ADS2006A)

Hi,

I want to simulate a single patch in order to find it input impedance (with ADS2006A). But I don't know which symbol is, so I attach a project using transmission line working like a patch antenna.

If this is the correct mode, I have other question. Thinking the air has an impedance near 120*3.1415 would I feed the tx line with a 50 ohms input impedance and a 377 ohms output impedance or must use 50 ohms for both sides?

Could someone help me?

Thanks,
Enric.

You need to work on layout.
Once the antenna is ready then create look alike and then simulate in schematic.
