A novel extremely wide band dipole antenna with omni- directional radiation patterns is investigated experimentally and numerically. The proposed antenna comprises two groups of crossed semicircular discs. The shape of each disc is modified to broaden the working bandwidth. Measured results demonstrate that the novel antenna achieves good impedance match from 0.45 to 38.9 GHz for S11lower than -10 dB, in agreement with simulated results. Omnidirectional radiation patterns keep stable at the frequencies concerned. The proposed antenna is highly suitable for various wide band systems.
