Hi,
can you give me more information ? For example what you need ? What type of antenna you can use ? - omnidirectional, directional, size, bandwith.....
You can use horn, conical horn, reflector antenna, microstrip antenna, dipol.... and so on...

So you need feed for reflector antenna ? I see on the left picture antenna, probably reflector antenna.
If you have circular waveguide (from your ODU unit), you can use some type of back feed (rear feed, hat-feed) for reflector antenna, for example follow this http://www.edaboard.com/ftopic340850.html
but you need 3D simulation software, the best is CST MWS.
