monitor的频率低于参考频率,是否远场的结果会不准确?

小弟仿真一个2g到4g的超宽带天线,设置了2g6g的monitor来看方向图和轴比,cst提示如下:
defined reference frequencyfor open boundary condition(4 Ghz) is laeger than the lowest relevant system frequency(monitor at 2Ghz)
please check open bandary settings to ensure accurate monitor results for the lowest frequency of interest.
请问这是否是说低频(2g)的结果不准确?该这么解决呢?

默认的边界是根据中心频率计算的,低频处增加的空间就不够了
你可以在边界设置中的open boundary里面修改
不改的话一般问题也不太大
谢谢你的回复。
改了以后对轴比有一些影响,对s参数也有一些影响
不客气,如果影响明显的话那就需要改
