CST仿真贴片谐振器的port及边界问题
录入:edatop.com 点击:
贴片谐振器如下
问题一:
在用本征模仿真器仿真模式时,若不设置端口,则正对贴片上方的电壁紧贴着谐振器,是否应该在本征模仿真的时候保留端口?
问题二:
当保留端口使得谐振器在一定边界下谐振,当改变微带基片的边长使之增大时,即减少电边界对仿真结果的影响,本证模仿真出的结果不同

上面第一组数据是边长为80mm,第二组的边长是100mm,
我想问的是,贴片的尺寸和基片面积在多少比例下,仿真结果是可信的?

我想问的是,贴片的尺寸和基片面积在多少比例下,仿真结果是可信的?
return loss中振荡点频率是怎么算的啊?
仿真可信度和模型尺寸有什么联系吗?仿真是否准确取决于仿真参数的设置是否正确(在模型尺寸正确的前提下)。
