Hi, everyone, I want to use HFSS to simulate the antenna array. I set the ports for each antenna element, but the pattern looks like a single antenna element pattern. I guess if it is because I did not set all the exitations at the same time. I don't know how to give the antennas exitations at the same time. It is not infinite array. If someone who know how to set corrent exitations for antenna array, please help me!
Thanks a lot!

I'm not sure how to excite all the ports at once (my HFSS array designs have used corporate feeds) but I know you can solve a single element, and then see what it would be like if it were part of an array. After you've finished solving, go to 'radiation' and then 'array setting' and then you can say how many elements, and how far apart they are etc.

What you need to do is to go to "Field Overlays" tab and then click on
"Edit Sources". You'll see that only 1st port has magnitude of 1 while
the rest have magnitude of 0. So you set all other to either 1 for
uniform amplitude didtribution or some other value according to
your design goals.
