Abstract
The invention relates to a panel antenna comprising: a ground plane (P); a dielectric substrate () having a permittivity (∈), the substrate () being located on the ground plane (P); at least one radiating source (S), each radiating source consisting of a plurality of antenna elements (E), the antenna elements (E) being located on the substrate () and furthermore consecutively spaced apart, relative to one another, by a distance (d) shorter than one wavelength λ, the wavelength λ corresponding to the antenna operating frequency. The antenna is characterized in that it furthermore comprises a dielectric superstrate () having a permittivity (∈) higher than the permittivity (∈) of the substrate (), the superstrate being located above the antenna elements (E), and in that the antenna elements (E) are all identical and have, in operation, identical radiation characteristics.
