Wireless telecommunication network antenna

Abstract

The invention relates to a multiband antenna, in particular for wireless networks, comprising:—a ground plane (7) extending along a longitudinal axis (A),—high band radiating elements (9a) set at the extremities of crosses, inclined at 45° with respect to the longitudinal axis (A), with an arm length being a dyadic fraction of a high-band wavelength (OHB),—low band radiating elements (9b) set at the extremities of crosses, inclined at 45° with respect to the longitudinal axis (A), with an arm length being a dyadic fraction of a low-band wavelength (OLB), characterized in that the high and low band radiating elements (9a, 9b) crosses are arranged along the longitudinal axis (A) of the metallic ground plane (7), in that the antenna comprises tubular separation walls (13) in electric contact with the ground plane (7), and in that the crosses are arranged in a pattern, wherein:—at least part of the high-band radiating elements (9a) are set inside the tubular separation walls (13),—the low-band radiating elements (9b) are placed around the separation walls.
