Abstract

A novel extremely wide band dipole antenna with omni-directional radiation patterns is investigated experimentally and numerically. The proposed antenna comprises two groups of crossing semicircular discs. The shape of each disc is modified to broaden the working bandwidth. Measured results demonstrate that the novel antenna possesses good impedance match from 0.45 to 38.9 GHz for S₁₁ lower than -10 dB, in good agreement with simulated results. Omni-directional radiation patterns keep stable within the operating band. The proposed antenna is highly suitable for various wide band systems.
