Abstract
The invention relates to a panel antenna comprising: a ground plane (P); a dielectric substrate (11) having a permittivity (∈1), the substrate (11) being located on the ground plane (P); at least one radiating source (Si), each radiating source consisting of a plurality of antenna elements (Eij), the antenna elements (Eij) being located on the substrate (11) and furthermore consecutively spaced apart, relative to one another, by a distance (de) 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 (12) having a permittivity (∈2) higher than the permittivity (∈1) of the substrate (11), the superstrate being located above the antenna elements (Eij), and in that the antenna elements (Eij) are all identical and have, in operation, identical radiation characteristics.
