HFSS 求模型特性阻抗

HFSS 求特性阻抗时  激励面waveport的位置和大小  应该怎么设置才算正确啊?我发现不同大小，位置的激励面，最后得出的结果也不一样
还有在扫描频率时  HFSS能不能仿很宽的频带  比如：从1-100GHZ
求各位大佬指点一二

fast模式不适合超宽带，改成interpolating或者discrete，discrete最准但是太慢了

Microstrip Port Sizing Guidelines
Assume width of microstrip trace is  w
Assume height of substrate dielectric is  h
Port Height Guidelines
Between 6 h  and 10 h
Tend towards upper limit as dielectric
constant drops and more fields exist in air
rather than substrate
Bottom edge of port coplanar with the upper
face of ground plane
(If real structure is enclosed lower than this
guideline, model the real structure！)
Port Width Guidelines
10 w,  for microstrip profiles with  w ≥ h
5 w,  or on the order of 3 h  to 4 h , for microstrip
profiles with  w < h
