Hello,in the cst manual which is presented bellow,they dont go to the specifics of the meaning of "combining results",i khow that there should be a phase shift of 90 degreen between the components in order to see if its right hand or left hand polarization. but what should i do specificly in cst to determine this? Or if i Plot in Ludwig-3 co
Hello,i would like to have the two orthoghonal modes TE10 TE01 and shift them 90 degrees to create circular polarization in the cst menu i can only choose the number of modes but i cant know which modes specificly will be generated.I can choose the polarization angle so by choosing two ports and 90 degree polarization i will only get two ortho
I use cst studio Thanks
If you really want to learn about the micro-strip patch antenna then pick any IEEE paper and try to learn how to design the same on cst or HFSS. I suggest this is the best way to gain knowledge. There are number of post, blogs and videos available online on how to design microstrip antenna.
Hi every one, I am simulating a horn antenna with a wave port with two orthogonal modes (to get circular polarization), the combine option in Post processing tab is not available for me. it gives me this warning:At least one propagating mode is not considered at port 1. Can anyone help me please? Thank you very much
There are tutorials out there on how to do this: just google it buddy:
I excite a fiber by circular waveguide with vertical S11 is vary good and I can monitor E-field along the fiber in arbitrary face in time interval.but this field in curve line per time is null. I need your help sincerely.
Hello all, I have been using cst for the past few days to design a PIFA antenna with circular patches, circular substrate I am doing stacking, by : ground plane -substrate 1- lower patch- substrate 2- upper patch- superstrate. However, I face this issue (see attached). I seriously, don't know which option to choose from and which is the (...)
I have a question about circular polarization analysis in cst MWS. I would like to simulate a structure in optical regime which converts from linear to circular polarization light. In some papers the authors evaluate the conversion (from linear to circular) efficiency by cst MWS. Do you think they use (...)
Dear All: I am trying to simulate a circular polarization input to a metamaterial-system. The metamaterials structure contains non-uniformly distributed unit-cells, so I have draw the complete structure (not a unit-cell) and used "open" boundary conditions. I hope the circular polarized beam incident normally to the system and transmit through
High axial ratio means linear polarization, low axial ratio means circular, but you can not tell which one is it (horizontal or vertical, RHCP or LHCP). HFSS can plot all these automatically, most probably also cst, just find it out.
hi; would anyone help me how I can define the radios of circular or the diameter of other types of bend coplanar wave guide port in cst. please help me as soon as possible I really need it

Dear Members: I have designed a 1x4 element antenna array in cst and now would like to study its beam forming on specific angles. The question is how can I calculate the relevant amplitudes and phases to achieve the maximum directivity of the array?? Anyone knows how to calculate amplitudes and phases and then implement them in cst??? Awaiti
So far - we appear to have struck out on this one. Whether it be HFSS, or cst, or any other, if there is a general approach on how to get a circular polarized wave going inside a waveguide (vacuum) cut out of a universe of PEC conductor, using ports..whatever, it would be nice to discover.
How to draw a linear helix with no change in radius in cst 2006. In cst 06 coils construction,linear circular helix option is not there.
Hi there, For an FSS unit cell designed in cst MWS, X-pol. and Y-pol. E-field probes can be used to check the cell's X-.pol and Y-pol. response. Now, if I want to check whether the designed FSS unit cell is producing any circular polarized response, how can I check that? Thanks in advance for your reply!
Hi, I have to optimize with cst studio suite a system of magnetically coupled resonators for wireless power transfer, so that the efficiency is maximum (therefore wireless power transfer between transmitter and receiver antenna is maximum). Each antenna is made of a number of circular loop (concentric), with a certain step. I have realized the an

Hi guys ...... I am a final year B.tech student in amrita school of engineering. I am currently doing my final year project in textile /wearable antenna which works for the GPS band:1575.42Mhz and Iridium band:1616Mhz. I am using cst for simulation. I have simulated a rectangular patch with a polygon slot for attaining circular polarization. I am o
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.
I want to get the polarization of the electric field after the light across some structured mental with cst MWS. how can I find it?
I suggest you set the model in HFSS or cst if possible.
Hi, I have build a circular waveguide with tapered extruded sections at each ends of the waveguide. I have also successfully simulated the design with 1 or 2 warnings and got results as well, but not quite sure of un
I have designed a cross dipole for single band in cst and achieved circular polarization with good gain. I need to redesign it for dual band operation. can any one help me out with the design concept for a dipole to be operated for dual band. Thank you
Before hiring time on kit that runs HFSS, AWR or cst, etc, it would be handy to know.. Can the port that is used to feed a circular polarized structure, say like a circular section feed-horn, be a simple linear polarized port where we simply expect 3dB loss? Can one stack drive ports on the same spot, with the polarization directions (...)
I am working on mode converter..i have two issues as follows:- 1.how to give a TM01 mode to a circular bent waveguide in cst microwave studio..? 2.how to check on the output different modes coming out of circular waveguide in cst. The dominant mode of circular waveguide is TE11. i want to plot a (...)
Hi Guys, I am using a substrate which is circular in shape in cst. The end of the TX lines has to be connected on to a wave guide port, but since I am using a circular substrate I cant use it, since freq domain solver does not support internal ports. Could you suggest me a way to simulate it ?
Hi, I am not sure to understand exactly your request. Your antenna has circular polarization RH or LH ? or linear polarization. Is a mechanical rotation and eletromagnetic field analysis ? Otherwise, with cst MicroWave Studio, it will be possible ! You need to compute the farfield and in postprocessing, you can analyse for each position.
Hi, Maybe you could use the 'E-field monitor' in cst MWS : then you can extract the E-field components with post-processing... Good luck...
Hi i am doing my research on conformal antenna design. i am designing an simple circular patch antenna using cst 2009 and trying to bend it, but the problem is i cant calculate the bending angle and radius of curvature. Basically, For which radius i will get which angle????? So will you guys give me some idea about how to calculate bending
Hello How can I create circular patterns with cst? I mean creating things like these: defining a shape or object and the number of times it's repeated around an axle. ---------- Post added at 22:39 --
Hi contactor. As shown by you, yes, you can define the ports 1,2,3 and 4 as you set - do this as follow: For every port assignment you will need to pick up 2 points: 1 is at the ground and the 2nd one is at the lower edge of the PEC port metal lines. You can simulate a 4 port model doing so. Or, you can assign for every ports a (+) sign or a
Hi all, I 'm doing a simulation of circular horn antenna with cst MWS. For the moment, I work with a linear polarization. But I want to generate a circular polarization. It's possible to create directly the polarization or should I put un septum behind my horn?? Thanks.
Hello everyone, I've designed an elliptical patch antenna in cst which works in the frequency of 5.8GHz. But I'm having problems determining whether it is radiating in circular polarization. If I'm not mistaken, for circular polarization the axial ratio must be 1 and if in ludwig coordinates, the field of vertical and horizontal must be in (...)
Were you able to solve this problem? Please post your .cst file. Thanks!!
I'm designing a rectangular to circular taper transition in HFSS and cst, but doesn't seem to get it right. How should I define the TE10 for rectangular and the TE11 for circular (they say this is degenerate but i dont undestand what that means) in cst? or HFSS? Can someone explain this to me, and how to do this properly? (...)
I'm trying to learn how to setup circular polarization in cst 2009 Microwave Studio for a plane wave. Assume a very simple dipole atten. Ground plane with feed (waveguide port over this feed), dielectric slab, dipole and then waveguide port 2 in front of the attn. How could I send a plane wave circularly polarized from port 2 in the negative (...)
Dear all, I am facing the problem of evaluating the INPUT IMPEDANCE of a slot inserted into a circular waveguide, which, as you know, it is different from Z11. The guide is terminated in one side with a wave port. At the end I have a two-port dev. As I used to do in HFSS, I wanted to define an output function: Zin=(1+S11)/(1-S11)*Z0 where S11 i

Hi all I am simulating a circular sector patch antenna in cst mws; it is excited by a waveguide port defined at the beginning of a microstrip line (see image)52786 Now what I can't understand is why if I reduce the dimensions of the substrate and ground plane, not only the total efficiency, but also the radiation efficiency fal
Hi, I want to simulate a patch antenna using 2 excitation signals with 90 degree phase shift to achieve the circular polarization purpose. I have read the relevent posts on the forum, however, there is no post mentioned where to add another signal and how to define the 90 degree phase shift. When I add new excitation signal, I can only choose t
