uwb antennaes 3.1-10.6 ghz

pls any 1 can upload UWB antennas (circular,hexagonal or rectangular....) with gain of 5 or above over entire bandwidth.thnkx in anticipation

do a google search on 2 - 11GHz log-periodic yagi or a vivaldi antenna design

tho not the styles you were specifically looking for, as you may find it difficult to do hi gain WB antennas in those styles

there's some good info out there :)

cheers
