design of cassegrain antenna, help!

Hi

i have to design a cassegrain antenna, with a circular horn feed.
i read in a paper that the design of cassegrain antennas has 8 parameters.
I just have the diameter of the main reflector and the f/D.
could you please tell me about the procedure for finding the other parameters?
and is it possible to simulate the design by hfss?
thanks a lot in advance

I think it is not possible to simulate it HFSS if the diameter is lager than 5 wavelength. I suggest using Feko, or TICRA POS, if you can get it.

Hi
thanks, and what about hte design procedure?
thanks

Hi saras

the perfect code for designing a cassegrain antenna is Ticra

look at http://www.ticra.com/script/site/default.asp
