cst antenna gain

Hi ...

I have designed a simple bow-tie antenna on CST... Altough i have the result of the S11...
I am interested on antenna Gain vs Frequency and phase response vs frequency.

What can i do to get the result of these parameter on CST ?

thanks in advance

Post processing->farfield->Gain
U can also choose u want to get max gain or in some specified or max direction. etc

do you know how i can plot h plane pattern and e plane pattern of antenna in cst?
