FEKO or CST to Analyze Side Lobes?

[GhS]

\Should I use FEKO or CST to analyze the side lobes of parabolic dish antenna fed by a horn waveguide?

Are there any steps required? Is it better to use MOM/PO of FEKO or T and I solvers of CST?

Thanks

I would prefer FEKO to do so, thus it is oriented well on such kind of problems. I havn't yet seen any practical results with CST's 'I solver' (just personal ocasion, if you have any - I would be glad to take a look), while with FEKO there are a lot of publications available on these topics.

What is the size of your antenna, btw?

First of All, thanks for your support,

My intention is Sidelobes reduction, I think that I’ll model a 60 cm center fed parabolic reflector, similar to the one that I’ll be working in real.

Can you provide me with some of the publications that were already done?

Thanks
