Creating farfield from GSM antenna in CST MICROWAVE STUDIO

I am new in this community and in this problematic.
I have to make a model of farfield of GSM antenna on living envirement. For that purpose I have CST MICROWAVE STUDIO.
For result I have to get a distribution of electromagnetic field in planes, on velocity of 1.5 m from the ground and to get table values that I can put in my report.
Any help would be appreciative, from building a project, geting informations from datasheets ( Radiated Power, Accepted Power, Stimulated Power, Re(E_Theta), Im(E_Theta), Re(E_Phi), Im(E_Phi),....) to geting results.
