DUAL-ANNULAR SLOT PHASE-SHIFTING CELL LOADED WITH MEMS SWITCHES FOR RECONFIGURABLE REFLECTARRAYS

Résumé

Reconfigurable reflectarrays require low-loss and lowdispersion active cells in order to achieve efficient beam scanning or beam shaping on a large bandwidth. The low-loss constraint is the more stringent as the introduction of tunable components (such as MEMS) in resonant phase-shifting cells may dramatically decrease their quality factor. In this paper, a comprehensive review of recent developments at IETR and TAS is carried out with the objective to dynamically control complementary resonant modes in a reconfigurable phase-shifting cell. The new topology consists of a dualannular slot loaded with 8 MEMS switches. It operates around 12 GHz and can provide four equidistributed phase states with low dispersion and low losses.
