Radiated Power
Radiated power is the amount of time-averaged power (in watts) exiting a radiating antenna structure through a radiation boundary.
For a general radiating structure in HFSS, radiated power is computed as
|
|
(1) |
where
• Prad
is the radiated
power in watts.
• Â
is the real
part of a complex number.
• s 
represents
the radiation boundary surfaces.
• E
is the electric
field.
• H*
is the conjugate
of the magnetic field.
• ds 
is
the local radiation-boundary unit normal directed out of the 3D model.
Note |
The accuracy of the computed radiated power depends on the accuracy of E and H. In some cases it is possible that the computed radiated power may deviate slightly from the actual radiated power. |
The accuracy of the computed radiated power depends on the accuracy of E and H on the absorbing boundary. In some cases it is possible that the computed radiated power may deviate slightly from the actual radiated power. To increase the accuracy of the radiated power, seed the mesh on the absorbing boundary.
