Group antenna with narrower side lobes in the horizontal plane

Abstract

The invention relates to an antenna device comprising a group antenna (310) with radiating elements (340-347) in M rows and N columns M, where N<M, which group antenna (310) has a width measurement (b) and a height measurement (h). The group antenna (310) is so arranged in the antenna device that the projection (P) of the group antenna in the sideways direction of the antenna in the horizontal plane (210) exceeds the width measurement (b) of the group antenna, whereby the group antenna is given a narrower main lobe in the horizontal plane (210). A group antenna according to the invention can, in addition, be incorporated in an antenna device (500,700,800) which comprises an additional number of similar group antennas (510-532; 710-720; 810-820), arranged on the antenna device along a surface (730,830) that is circular or a part of a circle, arranged in such a way that the respective projections of the additional group antennas in the sideways direction of the antenna in the horizontal plane also exceed the width measurements of the respective group antennas, whereby the additional group antennas are given narrower main lobes in the horizontal plane.
