help regarding excitation in HFSS project

In my project i have 3 antennas, onr for 145MHz and two for 435MHz (at slightly different frequencies). I am using HFSS to simulate my antenna. Now i have used 3 excitations one for each.
how can i see the radiation pattern of antenna due a single excitation alone, as i did not get any option in HFSS which allows to see the radiation pattern by choosing for which excitation we want to see the radiation pattern and is this the case that the radiation pattern shown is the total radiation pattern when all the excitations are at same frequency?
please help regarding this problem.

Awaiting for replies
