Where can I get program or software on antenna synthesis?

I want to design a low side-lobe array antenna, and the Dolph-Chebyshev method will be used. I had written some program on that method but I had lost them. I had not enough time to rewrite those program, so my friends can you tell me where I can get programs or softwares to synthesize the array antenna.

Thank you very much!
