I need help with cst Microwave studio. I want to know how we can plot a frequency Vs output power graph.
Say by measuring coupling S21 with a test antenna and in post process template converting this to power and plotting . Is this possible , or by writing Macros.

I have two simulations in cst-MWS and I want to compare the S11 on the same graph but they reside in different project directories. How can I import the other soultion to the current project and view the results on the same scale ?
PS : I have done with Matlab but MWS display is cleaner and I want to use that.

Hi, I have a simple question about cst. Are there any build-in macros to output the 1D result such as S matrix, Z matrix and Y matrix into txt file?? If no, are there any examples in the help or other resource online talking about how to write VBA macros to output? Thanks.
Any information will be appreciated.

i am simulating periodic structures with the cst. I am using the eigen solver to get one graph with phase vs frequency. it is suppose that there is one relation between the phase 0-360 degrees with the parameters Γ, M, X.
can somebody explain me how i can related these parameters with the phase and what this parameters mean???
thanks for you

In cst i read that the frequency domain solver is better used with structure having dimensions less than the wavelength. So i had my sturcture and got good results using Frequency domain solver. I tried to simulate the same structure with Transient solver but results were so bad... Does anyone know why is that? and is there a solution

I am working on some modifications of horn antennas in cst MWS 2006. I have 3 parameters or let's say 2.
I can use Par.sweep for one parameter and than change another manually, than combine results in MATLAB. It is annoying and take a lot of time:(
I run parameter sweep and set for example:

to see the axial ratio in cst, you should look at "Farfields" section in the simulated results... there should be a drop down list after simulating the design.
if you click on that drop down list you should be able to see the axial ratio plot...
The default plot is in 3D format, if you want to plot it on

In my opinion, the Negative step (step 2) is really not necessary. If the solids you draw are all PEC, just import them into cst, set the background material to be free space, set the objects imported to be PEC. Then cst is "smart" enough to know that the fields needs to be solved are in your "Negative" region. Similar thing happens when using HFSS
