Abstract
A communications antenna structure, e.g. for a cellular radio base station comprises first and second bent folded monopole planar antenna elements mounted on a ground plane and disposed generally perpendicular to thereto. The antenna elements are mutually spaced from each other and are disposed with their respective planes at an angle to each other whereby to provide both polarisation diversity and space diversity of the antenna structure.
