HFSS measurements and results comments

What are the basic antenna parameter measurements wiht HFSS, input impedance, resonans frequency, radiation pattern, bandwidth? And, I can' t find how I measure the bandwidth of a msa in HFSS. I found the resonant frequency graphics but not any other. How can I interprit the result graphics? For example, in the attachment, can I say the resonant frequency of the antenna is 7,05GHz or more?
