Thanks Stefan VE4NSA for the web address. This appears to be for a 2.4
GHz antenna and I have found many sites with such designs. The author
explains how to scale the antenna for other frequencies. It's a good
site, but not quite what I was looking for and that's probably my fault
for not making myself clear enough.
I have been looking for more generalised information explaining the
principles and operation - something explaining how to calculate size
and spacing and explaining why the calculations are made this way.
Thanks John AA1YE for the pointer to the book by Robert A Sainati. I
know my local library doesn't have a copy as I have borrowed the few
antenna design books they have several times. Technical books are, alas,
disappearing from library shelves. However, with the information
supplied I can ask them to try and find me a copy using their
"interloan" system. If it's what I want, I'd happily buy a copy, but
like to know that first (hi hi).
Thanks for the help guys.
