your gain plots are in dB (-4 to -1 dB), these correspond to gain <1; not negative.

hello rntsay
thanks for reply
just a question
How we can improve the bandwidth of axial ratio(for circular polarization)
is it possible we reach 1GHz bandwith CP for this antenna?
 

sorry but that's well outside what I know. I don't think it's an easy problem
even for experts.
