CST MWS中Realized Gain与Gain (IEEE)有什么具体区别？

利用远场计算结果计算时。选择realized gain与 ieee gain有什么区别？貌似 ieeegain大一些？请问为什么？哪个更准？

 

这个问题同问，也没有答案

 

帮助文件《Farfield Overview》，里面有详细的说明

 

我的cst打不开help能否把内容 复制一下。谢了

 

Gain (IEEE): Accordingly, the gain is defined similarly but is related to the input or accepted power of the structure. In the case of a loss-free antenna (no conductional or dielectric losses), the gain is equal to the directivity. Note, that power flowing out any port is not considered as accepted by the structure.
Realized Gain: The realized gain is defined by gain * (1 - Balance^2), it includes the impedance mismatch loss.

 

我的理解，Gain（IEEE）在这里不考虑S11，而realized gain考虑了S11.不知道对否。

 

应该是这样的。谢了。
