hi plasma,

ur article is a real help, atleast it gives some idea on how we can feed a ebg backed archimedean spiral antenna in reality(and not with some virtual excitation for em simulation purpose), otherwise i was in the middle of nowhere.

hoping for some more insight from u(including ur opinion) on this matter, to make it clearer and make it work actually.

with regards
abhi
