What exactly are you trying to design?
At a top level, the design of a parabolic reflector is very straight forward and can be done yourself on Excel. The profile is just the formula for a parabolic curve. The ratio of focal length to diameter should be around 0.6 for optimum efficiency.

Any text book will give you the gain for a given wavelength but is approximately
Gain = 17.5+20*LOG(F*D) dBi
where F is in GHz and D is in meters.

One of the basic books is S.Silver
Samuel Silver. Microwave Antenna Theory and Design, volume 12 of MIT Radiation Laboratory Series. McGraw-Hill, New York, 1949

I can give you more help directly by email

If you are doing a detailed analysis to consider phase errors for example and their effect on sidelobes you something like Jassik or Skolnik.

The software suites used are based on Geometric Theory of Optics (GTO) but I do not know of a commercial package. A Google with those key words might give success

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The Internet was still largely an unknown entity at the time and not much was available in the form of WYSIWYG ...
