That's a very true statement. It's almost impossible to match a 2.4
Ghz antenna to a circuit board unless you have a lot of UHF/Microwave
experience. Making it work on the bench is one thing, but making it
work well for a mass production board is a lot more difficult. I'd
definitely recommend that you pay an RF engineer to help you.
