利用遠(yuǎn)場(chǎng)計(jì)算結(jié)果計(jì)算時(shí)。選擇realized gain與 ieee gain 有什么區(qū)別?貌似 ieee gain大一些?請(qǐng)問為什么?哪個(gè)更準(zhǔn)?
這個(gè)問題同問，也沒有答案
幫助文件《Farfield Overview》，里面有詳細(xì)的說明
我的cst打不開help 能否把內(nèi)容 復(fù)制一下。謝了
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）在這里不考慮S11，而realized gain考慮了S11.不知道對(duì)否。
應(yīng)該是這樣的。謝了。
