Abstract
A ground plane for an antenna comprises first and second planar conductors (102, 103) arranged substantially perpendicular to a central axis of the antenna joined together and spaced from one another by a third conductor (104) arranged substantially concentric with and parallel to the central axis. An edge of the first planar conductor (102) is radially outward of an edge of the second planar conductor (103), and the second planar conductor extends radially outwardly from the third conductor (104) a distance of substantially one sixth of a wavelength of an operating frequency of the antenna.
