(help) coaxial feed in CST MWS

[bhw24]

Hi guys,
I am trying to feed a microstrip patch antenna with a coaxial probe feed. Till now I m getting nothing although I have read the circular patch antenna tutorial provided in the help manual.

Could anyone please suggest the correct method.
I am using CST MWS.

im facing the same problem too right now.

Check out the macro called 'Calculate analytic line impedance'. I noticed that this comes with a 'Build 3D model' option in the latest version of CST.

Otherwise, you can post your original file here and I can take a look.

hi thanks for you reply.
i'm giving up on coax feed and now i'm working on microstrip line feed.
but now i'm having a problem where the antenna need to be measured under bending condition as it is a textile antenna.
i don't know how to bend the patch antenna using this cst software.i'm really appreciate if you can help.
i'm trying to upload the cst file here so that you can take a look. but failed.it says ''invalid file''. huhu

You need to take a look at the solid creation options like blend, chamfer and imprint.

The 'imprint' operation is most probably what you are looking for.

Create a .zip archive containing your CST file and then upload it. That should work.
