ADS的版图仿真 手绘问题

没有高手帮忙吗
急啊急啊

用HFSS比较容易做.

这个我知道
但是我们的要求就是用ADS

还是没人帮忙
。

filter蝈蝈用IE3D来仿应该会比较精确一点

我不懂 不过只是提议
切换到cond2层之后画一个行么
在底层画铜层呢
好像protel中可以这么做啊

我画了 不过仿出的结果不对 和预想的结果差很大不知道 哪处问题
我就是用COND2层画那个框
不知道什么问题有高人知道吗？

地参考面没设置好，所以仿真出来的结果不对。

这个倒不难，主要就是两个端口参考地的设置。
Defining a Ground Reference

file:///D:/ADS2006U3/doc/images/eesof_web_search.gif Ground references enable you to add explicit ground references to a circuit, which may be necessary if no implicit grounds exist in your design.
Implicit ground is the potential at infinity, and it is made available to the circuit through the closest infinite metal layer of the substrate. Implicit grounds are used with internal ports and with single ports that are connected to objects on strip metallization layers.
There are instances where the distance between a port and its implicit ground is too large electrically, or there are no infinite metal layers defined in the substrate. In these cases, you need to add explicit ground references to ensure accurate simulation results. For more information on using ground references, refer to "Simulating with Internal Ports and Ground References".
You can apply ground references to the surfaces of object. The object must be on strip metallization layers.
Note Multiple ground reference ports can be associated with the same port. To be associated with a single port, the ground reference port should be a port attached to an edge of an object in the same reference plane as the single port.
To add a ground reference:
1.
Choose Momentum > Port Editor.
2.
Select the port that you want to assign as the ground reference.
3.
In the Port Editor dialog box, under Port Type, select Ground Reference.
4.
Under Associate with port number, enter the number of the single or internal port that you want to associate with this ground reference. Make sure that the distance between the port and ground reference is electrically small.
5.
Click Apply.
