CST MWS遠場方向圖結果中的tot.effic表示什么？

仿真天線時輸出的遠場3D圖形。
結果中的 rad.effic 是不是 輻射效率 = 輻射功率/凈輸入功率？
還有個 tot.effic 表示的是什么？

rad. effic = Radiation Efficiency
tot. effic = Total Efficiency
CST MWS幫助文件《Farfield Overview》。

謝謝了，但是我裝的CST 2009的Help用不成。
總是出錯

應該怎么解決help出錯這個問題?

是不是裝得什么“精簡版”的CST？這年月外行人亂精簡，真正有用的東西被精簡了……。
替你抄點兒吧：
Radiation efficiency: The antenna radiation efficiency is defined as the ratio of gain to directivity or equally the ratio between the radiated to accepted (input) power of the antenna:

or

.
Total efficiency: The total efficiency is defined as the ratio of radiated to stimulated power of the antenna:

Compared to the input power, the stimulated power considers any occurring reflections at the feeding location.

這個我也不知道
