Design of a high-resolution microfluidic microwave MEMS phase shifter

In this article, a novel microwave microelectromechanical phase shifter based on a microfluidic design is proposed and demonstrated. The design principles, the fabrication process, and experimental results (S-parameters and phase shift plots) are presented. The proposed system has a high bandwidth, high-power handling capacity, and a high-resolution along with a small settling time.
