[案例实践]同轴馈电长度的相关问题

Yes , From then ,I kown that  the  mesh Settings  is very important when we do some simulations.

Just read the Help files about "waveguide port overview" and the very bottom part it says: ,`)!K}2

Furthermore, for the realization of the waveguide port mode operator in the transient solver, it is necessary to have some equidistantly meshed region in front of the port, namely three mesh steps as shown in the picture on the right. This grid distribution in front of each waveguide port is automatically considered during the mesh generation and cannot be deactivated.

If the above mentioned condition is not automatically fulfilled by the mesh generation, it is useful to apply local mesh settings to achieve an equidistantly meshed region. ci6j"nKci  

I'm  so sorry  that the "long tail" is necessary.But by do so,the error has gone.  Thank you!

You  have teld me a secret that if I want to have a good comprehension of the software,  the "help contents" is really a good meterial.Thank you!

太聪明了，我就只会增加同轴长度。

谢谢 学习了 我想问一下的是若要求输入阻抗是50欧，则这个同轴线的尺寸之间有一个什么样的关系了？包括那个接地板

从哪里的输入阻抗？ W(jXOgs+_

建议熟悉传输线理论，建议阅读《微波工程》里同轴线的章节。

可以利用CST的Macros內的Calculate裡的Calculate analytical line Impedance做調整計算 r6b;v2!8
