CST MWS中的相位方向图为什么不连续?左右反相?

用CST仿真了一个喇叭,看到喇叭的主极化分量的相位方向图关于最大辐射方向反相,不连续,这和HFSS仿真结果完全不一样?为什么?请教
理论值应该是连续的么?
对,应该是
我记得在那个相位图上点右键,Plot Properties里点一个wrap Phase的勾就好了,小编试试。
CST里的相位就是在0~360之间的,其余的都会翻上去或者翻下来。
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).

虽然很咯人,但是确实这样
PS:一般的天线两边相位应该是对称的,只是有跳变而已
木有找到啊,要是有这个就好多了,这个反向相当格人,今下午老板要看相位我还特别给解释了CST中是反向的
