Abstract

An omnidirectional wide-band antenna which operates with simultaneous horizontal and vertical polarisation consists of two truncated conductive cones which operate as a bi-conical antenna and each truncated cone is associated with a conductor array perpendicular to the axis of the cones. The conductors are in the form of logarithmic spirals.
