摘要：

The ways to solve a problem of providing stable operation of microwave ferroelectric phase shifters for steerable antennas in a wide temperature range are briefly considered. A ferroelectric phase shifter based on cascaded tunable ferroelectric planar capacitors is properly described. The connection of the tunable capacitors in series with transmission line sections allows obtaining a voltage tunable phase shift, which practically does not depend on temperature in the range 250-350 K. Such phase shifters can find a wide application in phased-array antennas.
