Hi there
I wana design a filter using ADS Momentum 2011, I simulated some structures. Now I want to optimize some filters, you know by changing the width, length and etc in layout to meet good performance. My concern is about microstrip filters.
BTW I saw some examples but they define a parameter such a width (it's just defined and no TL's width define as so) then transform the design to schematic and optimization done in there, sth weird?!
So is optimization possible in layout or not?
In either method HOW?

Thx alot
 

You can optimize your layout in both ways, just with layout or with layout and schematic. Both is documented in ADS help!

Thx buddy...
But you know there is no documented thing about optimization in layout, could you give me a lead?

thx again
 

Agree, but it is written (Simulation->Electromagnetic->Defining Component Parameters and Using an EM model) how to set parameters, which you can use in a schematic for optimization.
 


Thx again...
Consider this image, it's part of a filter, red rectangle illustrates aperture on the ground and gray rectangles are microstrip.
Here is my question: can we have the Schematic of this filter, I mean draw this filter with aperture in layout (which sth I can do) and convert it to Schematic for optimization?
I tried but I could not, can you give me a lead?
Thx alot buddy
 

Ah ok, as I understood you want to simulate defected ground structures?! I think this is not possible with schematic symbols. Maybe it is possible (if you consider the attached pdf) to use for the bottom layer not stripped layer but sloted layer. Than MAYBE it is possible to use schematic symbols with different layout layers!
