Help!! Obtaining gain IN HFSS

hello i simulate a dipole with ansoft...

i have no clue in gaining the gain of the dipole

the gain of a dipole should be in dBi or dBd

why in ansoft don't have that function...

if i used the gain in dB...

Theta [deg] dB(GainTotal) [db]
Phi=0deg, Freq=2.45GHz
Setup1 : LastAdaptive
0.000000 -49.705968

170.000000 -17.453341
180.000000 -31.415533

as i know 1 dipole have a gain 2 dBi.....

what should i do?
can anyone explain this

thx before

You need to post your project...there is something wrong in your setup
