CST MWS中的相位方向圖為什么不連續(xù)？左右反相？

用CST仿真了一個(gè)喇叭，看到喇叭的主極化分量的相位方向圖關(guān)于最大輻射方向反相，不連續(xù)，這和HFSS仿真結(jié)果完全不一樣？為什么？請(qǐng)教

理論值應(yīng)該是連續(xù)的么？

對(duì)，應(yīng)該是

我記得在那個(gè)相位圖上點(diǎn)右鍵，Plot Properties里點(diǎn)一個(gè)wrap Phase的勾就好了，樓主試試。
CST里的相位就是在0～360之間的，其余的都會(huì)翻上去或者翻下來。

Testing the Phase center result: You may check the behavior of phase by entering the phase center result coordinates as new Box origin and then plotting the phase. Because the spherical unit vector theta changes its direction in the most interesting point around the z' axis, the E-theta phase has a 180 degree phase jump at theta = 0. It is therefore recommended to switch to the Ludwig3 representation of the farfield to check the constant field around the z' axis (around theta = 0).

雖然很咯人，但是確實(shí)這樣 PS：一般的天線兩邊相位應(yīng)該是對(duì)稱的，只是有跳變而已

木有找到啊，要是有這個(gè)就好多了，這個(gè)反向相當(dāng)格人，今下午老板要看相位我還特別給解釋了CST中是反向的
