comparison of simulated and measured radiation patterns

i am wondering whether anyone of you have experience of comparing the simulated radiation pattern in CST MWS/HFSS with the measured one.

i want to compare the E plane and H plane patterns

i m exporting the radiation pattern simulated by CST but i dont understand how can i export the dB values normalized to the maximum value as the measured values are normalized ones

i would appreciate any comments on this problem

regards

for this case there r no option in these two softwre if u want to compare then u must export both file in MS office excel then normalized and plot them.
