Dear Luke,
I am assuming you are talking about parabolic antenna. Well the first thing u need to know is the required gain, which you may calculate from the link budget. Once u have that, u can use the formula
Gain=20log (7.4 D f )
Where D is ant dia in mtrs
f is freq in GHz.
Does that solve ur purpose ??
