Looking for info about analysis and design of a planar archimedean spiral antenna

Hi everyone,
My name is Tope, a final year student of the University of Lagos, Nigeria. I need ur assistance on how to go about the "analysis and design of a planar archimedean spiral antenna over a finite ground plane".
I would be very grateful if anyone could help me out with this project topic. To whom it may concern, it is very urgent!
Thanks in anticipation for your response.
Tope a.k.a. Jupiter

search papers in ieee website, and study antenna books, it is very mature theory.
