Error when doing simulation on CST for 30GHz patch antenna

[lokman.ibrahim]

Hi, i am newbie in designing an antenna. i try to design a microstrip patch antenna at 30GHz using CST. i manage to design the antenna but when doing the simulation for far field some error message was detected. please refer to the attachment file. anyone can help me to solve or guide me about this error? it is that i miss some setting on CST. this is my first time using this software.

It's not an error. It's a warning. It means that there are some modes supported by your port which are above their cut-off frequencies. For this kind of simulation I don't see that being a problem, but you may try to increase the number of modes included (at the waveport menu) to see (and make yourself comfortable) if it has any effect on your results, and this should also get rid of that warning.
