So far I beleive cst has the most extensive feature list. But still it lacks some very usefull features. hmm... maybe we shall make a wishlist for the next version of MWS.
Hi all, 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. Thanks fo
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
Hi, I would like to know how I can plot the diagram above using cst. well I have runed cst example which called Four Tissue Phantom Head. but I can't succed to plot the same picture.
Hi, I have an interesting problem to solve. I have coaxial resonator and I want find out its resonant freauency depending on temperaure. The influence of temperature ais modelled as alllenghts enlarementd depnding on one variable. The problem is that cst produces some jumps in the graph. Could anyone advise how to get rid of? I mean has anyone expe
Hey there, 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
Hi , 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. thanks GV
I 've done something similar quite long time ago so I will only guide you roughly and give you some ideas. Two options from me: 1) create a new folder within cst MWS results and paste there the required graphs. Make sure though that these are relevant, e.g. I don't think of course that you ll be able to paste rad. patter together with S1
hi, everyone. I have a question about the cst MWS. Are there any ways to plot the axial ratio of the antenna at a specified angle as a function of frequency? If so, do I need to setup the far field monitors for the frequencies before the simulation? Thanks.
hello shameemkabir well thanks for your reply but i think you havent read my question carefully. i know how to define frequency monitor for surface current/H field or any other farfield parameter in cst to make it simple my question was how can i plot a graph in which frequency is along x axis as in S paramter plots but surface current in mA
hello when we terminated any antenna in direct contact with the lossy slab then how can we see the field distribution in the all three direction in the slab due to that antenna in cst microwave studio and also tell me how can a plot the graph between the electric field distribution in all three directions with thickness of slab in cst (...)

Hi i think best way is to export the S parameter data from cst and HSs and then plot them in one graph using any data plotting tool e.g Excel i hope this is helpful regards
Hi! I am trying to solve the following problem: plane wave excites a sphere made of Ag placed in free space. Boundaries are opened, for Ag I use the drude model in optics. I place a broadband farfield monitor and get a field depending on teta and phi in far zone. 2 questions: 1) The field I got - is it the sum of scattered + incident, or
One of the methods in optimization of an antenna in cst is writing a program in VBA and implementing an optimization method. Good Luck
hi all iam new in using cst i want any one tell me the steps to draw this file in cst thanks for all
in our company, after the antenna design is finish in cst, we counter check the antenna using our network analyzer. in most cases our cst result for S11 is much better compare to the real measured data by the analyzer. in cases of the transmission pattern we go out and test outside to see where we transmit and recieve well...
6.- Edit "license.dat" and replace "server_name" with your computer name and "000000000000" (replace all) with your HOSTID (Mac or Physical Address). Did you replace all of the zeros with your hostid? Maybe you missed one. On with windows system (XP 64 bit or Windows 7 32 bit....)do you tr
have u noticed that the 3D results (graph) for the far field in the single dipole example of cst MWS dont make sense? the E field appears to be dependent on phi ...... i constructed a new single dipole myself, and the results are again dependent on phi!!!! i am using the transient solver, of course. help anyone..... tnx
Greeting. I am using cst studio 2010. Currently I am designing a planar antenna for dual band GSM and single band WiFi. I am modifying a triband antenna from an example, whose S parameter value are very prefect, just the frequency values are not accurate. I wish to shift the frequency graph to my desired frequency domain which are 0.9, 1.8 a
Hi, I'm trying to simulate a frequency selective surfaces in cst MWS. I am using Frequency solver with floquet mode boundaries, meaning I choose unit cell for X,Y and open (add space) for Z. Right now I'm only interested in transmission coeff. for zero incident angle, so I select only the first 2 floquet modes TE(0,0) and TM(0,0) for excitatio
hello all, do anyone know how to combine the results obtained in cst . for example iam getting S11 for two cases 1.with EBG and 2.Without EBG how to combine these graphs in a single graph with annotations as appearing in ieee papers. pls reply soon if anyone knew..I've to prepare a paper for conference this month.
Hi kristal, 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
hello i am new in using cst studio. can anyone say how i can use the figures in cst results and also the sturucture of my design be imported in a document for repoting. and how can i access the data files for calculation in MATLAB?
hello, I have done the simulation of small dipole using cst microwave studio. The photo of E-field plot is attached. 1. can anyone help check if it is correct? I know that small dipoe only has E field in theta direction; it should be zero in the phi and r direction of a spherical coordinates. Does my graph show that? I am confused because I see

How would I create multiple curves on one frequency graph with each curve representing a different diameter for the antenna. I would like to have a plot of impedance vs. frequency with several curves representing various antenna diameters. Added after 5 minutes: This question involves using cst microwave s
Ridge & corrugations are different geometries. I think both serve common goal make the horn broad band & provide smooth transition Ridge is kind of drawing cruve first on graph paper first. Then use points of that graph & use plot point in HFSS Join all points to make curve. This is one of the way. Be the way you have any documentation o
hi friends I'm new to cst MWS. I have designed single arm spiral antenna and feed by microstrip line as shown below. I got the frequency VS S parameter graph is not a proper one. I don't know why it is. I want to get frequency VS radiation graph and frequency VS returnloss graph. How can I get it using (...)
i want to match an impedance to 50 ohm. i simulated a stub matching network using cst and saw the smith chart. At my required frequency there was good match but, the shape of the smith chart (its connecting impedances at various frequency) was like a sharp spike. the tip of the spike is at 50 ohm at my freq and the spike is coming out from a circle

But my problem is, i would like to plot the s11 for different ground slit length..namely 3 mm, 4 mm and 5 mm.... How to do this so that I
need help in combining the results of an antenna simulated and measured.antenna simulated in cst microwave studio and tested in network analyzer for VSWR and radiation patterns in anechoic chambers
I recommend you can use a commercial software such as cst or HFSS or ADS. all of them calculate the axial ratio easily and you don not need to do anything.
