【Abstract】 Ferroelectric thin films phase shifters which are analog phase shifters with fast response speed,low cost,low power consumption and relative small size are quite suitable for phased array antennas,especially conformal array antennas.In this paper,the structure,principle,performance and character of four kinds of typical ferroelectric thin films phase shifters are introduced.It’s point out that distributed ferroelectric thin films phase shifters and all pass network ferroelectric thin films phase shifters have good prospects.The status of the research and problems are summa- rized.Some suggestions for the future exploration and research are presented.更多还原
