從ADS Model 轉(zhuǎn)到CST 設(shè)定上的問(wèn)題.

大家好 有問(wèn)題詢問(wèn)先進(jìn)
我在練習(xí)RFID TAG的題目
一開(kāi)始是用 ADS做練習(xí) 結(jié)果與實(shí)際測(cè)試接近
然後再用CST2006 做練習(xí)使用從import ---->ADS Model方式呼叫檔案
結(jié)果都有很多Warning

想請(qǐng)各位幫忙看一下 并指證我哪里設(shè)定錯(cuò)誤
謝謝各位

Stimulation at port 1 (mode 1)
--------------------------------------------------------------------------------
Units settings:
Dimensions: um
Frequency:GHz
Time: s
--------------------------------------------------------------------------------
Mesh summary:
< 0.5 :0.3%
< 0.25:0.2%
< 0.1 :0.1%
< 0.05:0.1%
< 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

Subcycle statistics
Number of components in total: 1061396
Number of subcycled components:62875

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.
