design coaxial line or waveguide to feed dish antenna at CST

Hi,

I need to simulate at CST preformence of reflector (dish)antenna
(that have the dimension of d=12cm,f=8cm,freq=34.3GHz)
and compare to the specsification of the real one reflector antenna

I am using the the tamplate from :macros\constract\online\reflector dish
but in this tamplate there isn't a feeding point (coaxial line port or waveguide port)for the reflector antenna

Can someone post this design of feeding point (coaxial line or waveguide port)for the reflector antenna?

Thanks
