I happened on this "book preview" on Google book search:

http://books.google.com/books?id=xTS...sult#PPT449,M1

It points to pages in Antenna Handbook, Jasik and Johnson discussing spirals and at least one construction.

which software do you intend to use?

I think I should go for HFSS.
do you suggest any other for this design?
I also have ADS.

Thanks Azulykit
You are the best.

Latest version of HFSS will be of use and the mentioned book is sufficient for design of the sinous antenna

Do you have latest book?
Please upload it here if you have.

The latest is by Volakis. I have an autographed copy and it won't fit inside my cable connection.

I guess you might need to buy a copy or visit a library.

But you can share only small part of the liberary right?
I need only sinuous antenna part.
