CST simulation aborting (2 micro strip antenna)

[Kick]

Hi all,

In my design I am using 2 micro strip antenna. I have added 2 separate ports and signals for antenna. But When I am starting simulation, it's always aborting. Single antenna simulation is working fine. If anyone knows the reason please share here.

Thanks.

It is a common problem with cst. If you are trying to give phase difference you can make a wilkinson power dvider with one arm longer and feed the antenna from power divider.
