Dear sir's
please guide me how to extract the simulated antenna files from CST to fabricate antenna
It must have all the data that needed to fabricate, including feed connector details , PCB layout details, dielectric details, dimensions etc...
Hmm.. OK, taking this just the way it was asked..
CST is a simulator tool. Some examples might fit your desires, after they have been adjusted a little to suit you.
You can mess with it repeatedly, and invoke various optimization features to adjust dimensions to improve performance.
To fabricate such, you then go ahead and get the parts and build it, in the expectation that the performance will be similar to the CST design predicion.

Details of layout, dielectrics, etc, is data you supply yourself input into the CST simulation, as is also the dimensions, shapes etc. for the structure.
