HFSS15: Peak Realized Gain
录入：edatop.com 点击：
Realized gain is four pi times the ratio of an antenna’s radiation intensity in a given direction to the total power incident upon the antenna port(s). Peak realized gain, in turn, is the maximum realized gain over all the user-specified directions of the far-field infinite sphere.
The following equation is used to calculate realized gain in HFSS:
| 
| (1) |
where
• U 
is the radiation intensity in watts per steradian in the direction specified.
• Pincident 
is the incident power in watts.
Note | Because the gain is calculated from the input signal at the port, a port must be defined for this quantity to be displayed. |
