I am a beginner for the electromagnetic simulation software. I am referring to the attached picture.

The green and blue boxes(areas) have different permittivities. The bottom box includes an LC resonator with a planar coil inductor and a parallel plate capacitor. The top box is an antenna. In real life, I am connecting the antenna to a network analyzer and measure the s11 response. I want to simulate this model in a simulation software. The result I need is the s11 plot of the antenna.

1) Can I use ADS to do this simulation?

2) If (1) is a yes, can I import an autocad model to ADS and simulate?

Thanks in advance.
