A high-performance phase shifter for phased array antenna

Recently, expanding wireless communication systems have presented new challenges to design and produce high quality miniature tunable phase shifters with low cost. Dymas Research proposes a novel RF phase shifter fabricated on high-performance ferreelectric films to provide tunability for adaptive microwave devices. This tunable microwave device has the advantage of achieving frequency or phase tunability as well as small size. It is expected that the proposed structure will be attractive for developing miniature tunable microwave devices with fully planar fabrication technology. This is especially of benefit to monolithic microwave integrated circuits (MMICs) and growing microwave superconductive circuits.
