The invention relates to a telecommunications device with an electronic scanning array shaped according to a first surface with rotational symmetry, comprising: a first array of first radiating sources arranged over the said first surface in order to operate about a first central frequency. According to the invention, the device comprises, in addition: a second array of second radiating sources arranged over a second surface with rotational symmetry adjacent to the said first surface in order to operate about a second central frequency, the first and second sources being placed such that a first source and a second source do not face a second source and a first source respectively, along a section normal to the first and second surfaces pointing to the first source and the second source respectively. The invention also relates to a telecommunications terminal in a satellite constellation system and to a wireless communications terminal for communicating with domestic appliances comprising a device according to the invention.
Telecommunications device with electronic scanning arrays of the type comprising M first alignments of first radiating sources in arrays, the said sources being aligned along a generatrix of a surface of revolution, and a switch coupling the said M alignments to N lines of an array of combiners/dividers, where N<M, the said switch being controlled to feed N alignments amongst said M alignments at a given instant, said N alignments being chosen to be adjacent, said device comprising, in addition, phase shifters inserted between the radiating sources of the same generatrix and a controller to control the switch and the phase shifters so as to adjust the radiation pattern resulting from the said N alignments according to a first azimuthal direction and a second elevational direction, respectively.
