Re: simulating a patch antenna with HFSS

I would like to simulate a basic patch antenna with HFSS. But I have somme difficulties :
1)What kind of excitation must I take (incident wav, lumped wave ,....) ?
2) Should I choouse the PML boudaries ?

Can anyone help me to draw this antenna and to simulate it ? Thank you in advance.

Thank you

Aparently when someone write p.a.t.c.h antenna this system
change it to "fix", I assume because a patent regarding that
type of antenna
