hi, friends
Here I have problems for your help.
I want to creat substrate model of my PCB board in ADS.
As you see in attached files, signal lines is on the layer2. The ground is layer6.
On layer1,3,4,5, there is no singal lines and ground. Here I want to simulate this
kind of PCB exactly from 800MHz to 2 GHz. Below is my question:
1. The microstrip substrate is the most easy.But there is layer1 above layer2.
Is the simulation result exact using MSTUB if I skim layer1?
2.Of couse Multilayer Substrate is more exact but complex. And layer1,3,4,5 is no use for me but can't be deleted in practise PCB.
So I want to make things between layer2&6 as a whole substrate. During caculating substrate heigh and Dielectric Constant,
How to deal with the layer3,4,5? You see,they are actually no-exist for me.
3. The most important question: Could you please give some suggestion that which kind of substrate I should use?
Microstrip? Stripline? Multilayer?or others? If Multilayer, MLSUBTRATE(n?) should be used?
I am eager to get your response!
Thanks a lot
