when i use HFSS11 ,how shall I get Quality factor ?
for example when simulating a combination of fss array over patch antenna ,how shall I get the Quality factor of this antenna?
And for a common example ,when simulating a Resonator,how shall I get the Quality factor of this Resonator?
Thank you for your help

Thank you for your help
for quality factor measure you can calculate it by using formula
Q=(f0)/(f1-f2)
f0=Resonance frequency
f1 and f2=-3db point on return loss curve
so fron HFSS you can calaulte the return loss graph and from there you can calulate q factor.
hi there
well if i am not wrong the f1 and f2 are 3dB points rather than 10dB points in Q factor calculation
