Planar near-field measurement on an omni-directional UWB antenna

Abstract

In this paper a novel planar near-field measurement technique is used to characterise an omni-directional ultra-wideband (UWB) antenna. It is shown through numerical simulation and experimental verification that a full sphere far-field pattern of an omni-directional antenna can be obtained with planar near-field acquisition system. It offers a cost effective near-field solution to a class of antenna that currently can only be effectively served with spherical NF scanning.
