軸比頻率曲線的問題

好不容易弄出來軸比對頻率的曲線，但是發(fā)現(xiàn)貌似不太對。
一般情況下，軸比在0°是最小的，所以我想看的曲線是0°的軸比對頻率的曲線，但是仿真計(jì)算出來的軸比對頻率曲線不是很符合各頻點(diǎn)監(jiān)視器的結(jié)果。
請問高手這是怎么回事，該怎么設(shè)置。

是我得出的軸比頻率曲線，但是根據(jù)監(jiān)視器的結(jié)果，給個對比

誒圖片顯示出來了，那怎么把圖片穿插在文章里呢。

When you insert the figure, make sure the "[upload=x]" is at the place you want it to be displayed.
It seem they're close, but not exactly the same. So you need to know if this inaccuracy is in the tolerance range or it still need to be improved. Because it's farfield related, you'd better read previous thread which I remembered talking about farfield accuracy improvement.
