从ADS Model 转到CST 设定上的问题: L4.rar

大家好 有问题询问先进
我在练习RFID TAG的题目
一开始是用 ADS做练习 结果与实际测试接近
然後再用CST2006 做练习  使用从import ---->ADS Model方式呼叫档案
结果都有很多Warning

想请各位帮忙看一下 并指证我哪里设定错误
谢谢各位

Stimulation at port 1 (mode 1)

--------------------------------------------------------------------------------
Units settings:
  Dimensions: um
  Frequency:  GHz
  Time:       s

Mesh summary:
  < 0.5   :0.3  %
  < 0.25  :0.2  %

  < 0.02  :0.0  %
  Minimal filling: 1.021 %
--------------------------------------------------------------------------------
*** Warning ***
The current settings will propably lead to a very long simulation time.
You may improve the simulation speed by:
1. checking the frequency range and units settings
2. extending the simulation frequency range
3. checking the mesh to avoid very small mesh steps

Port: 1
*** Warning ***
Some higher propagating modes at port 1 are not considered in time domain
calculation. This possibly leads to an inaccurate energy balance. Consider to
reduce the port size or decrease the upper frequency limit.
