Abstract:
A vertical polarization antenna including a vertical support structure of elongate shape and a plurality of dipoles situated at different levels along said structure and coupled to a coaxial feeder cable, characterized in thatsaid antenna includes only one of said dipoles (1, 2) per each of said levels along said structure (3); and in that all of said dipoles are coplanar but are equally divided into two groups, one above the other, so that, when the antenna is used for transmission, inherent horizontal polarization components of the two groups are opposed and tend to cancel each other, said antenna further including a ground plane (5) disposed laterally relative to each group of dipoles, said ground plane having a first section, extending on and along a first lateral side of said one of said groups of dipoles, and a second section extending on and along a second, opposite side of the other of said two groups of dipoles.
