Abstract
The invention relates to a multibeam antenna for emitting/receiving a radiofrequency signal in a plurality of directions in at least one frequency band, the antenna including: a floorplan (P); a dielectric substrate () having a permittivity (∈), the substrate () being arranged on the floorplan (P); and a plurality of assemblies (E) of antenna elements arranged on the substrate (), each assembly (E) corresponding to a direction of the antenna. The antenna according to the invention is characterized in that said antenna also includes a dielectric superstate (), having a higher permittivity (∈) than the permittivity (∈) of the substrate (), arranged on the assemblies (E) of antenna elements, and in that the assemblies (E) are interleaved one under the other so as to form a column, the assemblies (E) corresponding to a single antenna direction being separated by a number of assemblies equal to the number of antenna directions.
