Max U
The radiation intensity, U, is the power radiated from an antenna per unit solid angle. HFSS calculates the radiation intensity in the direction in which it has the maximum value. The maximum intensity of the radiation is measured in watts per steradian and is calculated by

where
U (q,f) is the radiation intensity in watts per steradian.
|E| is the magnitude of the E-field.
h0 is the intrinsic impedance of free space — 376.7 ohms.
r is the distance from the antenna, in meters.
