How to give different feed for an antenna array in cst?

[Chandru B]

hi,
i'm working on CST software, designed an antenna array and i gave a feed and also simulated it but i need to give separate feed or port (i.e., port 1,2,3...) for those antenna also i need to simulate that array according to spatial modulation., anyone could help me plsss.... or whether it is possible to simulate according to spatial modulation?

In CST, you can just use math method to do so, post-processing, set the others ports amplitudes and phases, then you can get the results.

ya, i tried using amplitudes and phases in post processing but i couldn't simulated my antenna using spatial modulation., Is there any other way or software that could help me...?
