Abstract

L'invention porte sur un dispositif de dépointage d'un faisceau électromagnétique (Finc) comprenant au moins deux lentilles diélectriques (D11, D12) superposées, ledit dispositif étant caractérisé en ce que les lentilles diélectriques sont d'épaisseurs effectives variables, et en ce qu'au moins une des lentilles diélectriques est mobile selon au moins une direction (y) sensiblement orthogonale à un plan (xOz) dans lequel le faisceau électromagnétique est dépointé, ainsi que sur une antenne comprenant un tel dispositif. Elle porte également sur un procédé de dépointage d'un faisceau électromagnétique.The invention relates to a device for detaching an electromagnetic beam (Finc) comprising at least two dielectric lenses (D11, D12) superimposed, said device being characterized in that the dielectric lenses are of variable effective thickness, and in that at least one of the dielectric lenses is movable in at least one direction (y) substantially orthogonal to a plane (xOz) in which the electromagnetic beam is detuned, and on an antenna comprising such a device. It also relates to a method of misalignment of an electromagnetic beam.
