ABSTRACT:
A phase shifter module (CD), dedicated to a reflectarray antenna, is defined by a characteristic resonant length and, in at least one chosen place, 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.
