Vias in SIW slot array antenna

hi
I want to design a nonlinear Vias in SIW slot array antenna, According to the following.
anyone can help me?
Thanks

Please help me

you can design by duplicate angle

Thank you for your help but i want to design this structure in CST.
How can i design this structure in CST software?

Go to Objects/transform option.

In Objects/transform option, the transfer is done only on the main coordinate axes (x,y,z)!
But I want moving Via on a circular shape axis..
wave85: can you help me?
Thanks

in transform/rotate , there is an option for selecting the origin of rotation. if you could not see it, first choose transform/mirror then transform/rotate. don't forget to tick "copy" option.

Please tell me the steps from the CST software. I do not understand your description.!
Thanks

I attached a picture of my "transform box". check it, if you had any problem, don't hesitate to ask.
