some higher order propagating modes at port 1 are not considerded in time domain caculation .this possibly leads to inaccurate energy balance. consider to increase the number of modes or decrease the upper frequency limit,我现在仿真的频率到11GHZ但看不到截止带宽,到频率调到12GHZ时,就出现上面这种情况,请问高手,这种情况该怎么解决?谢谢!
最后一句不是给提示了吗?
是啊 如果降低频率的话,我就看不到截止频率了,增加模式结果会不准确的吧
为什么增加模式结果会不准确?把原因说出来。
增加了端口模式为3,选择solve--transient solver parameters ,将mode选为all后运行,出现了
hybrid modes exist at inhomogeneous port1 .this could lead to an inaccurate energy balance .
please check your structure.莫非是我天线的结构有问题?
天线频率范围?选的波导?
提示说的那么清楚,check structure!
是个微带线,天线的频率范围在3-11GHZ,调到3-12GHZ时就出现上面警告了
减小端口尺寸
en thankyou..
端口太大,容易激起其他模式。
