Abstract:
1. A phase shifter module (CD), for a reflectarray antenna, defined by a characteristic resonant length, characterized by the fact that, in at least one chosen place, it has an MEMS type device (DC, DC′), able to be placed in at least two different states respectively permitting and prohibiting the establishing of a short-circuit intended to vary said resonant length, in order to vary the phase shifting of a wave to be reflected presenting at least one linear polarization, further characterized by the fact that it has a resonant planar structure consisting of an upper patch (PS) placed roughly parallel to a lower ground plane (PM 1 ), at a chosen distance, said upper patch (PS) having at least one slot (FP) equipped with at least one MEMS device (DC, DC′) controlling the characteristic resonant length of said upper patch (PS), and further characterized by the fact that it has at least one auxiliary patch (PA
