Linear Polarization phasing cell length and variable resonance by mems switches.

摘要

phasing cell (CD), for a network of reflector antenna, defined by a characteristic resonant length, characterized in that it comprises a resonant planar structure comprising an upper patch (PS) placed substantially parallel to a lower ground plane (PM1) to a selected distance, and it comprises, in at least one selected place, at least one micron electromechanical device MEMS (DC, DC ') controlling the characteristic resonant length of the said upper patch (PS), the MEMS device and it can be placed in at least two different states allowing and prohibiting respectively the establishment of a short-circuit intended to vary the said resonant length, so as to vary the phase shift of a wave to reflect wherein at least one linear polarization.
