N2 - This study presents the design and loss assessment of a tunable, phase shifting coplanar waveguide (CPW) line. The phase shifter consists of a CPW transmission line with a metallic loading strip suspended on top. The gap between them can be precisely altered with the use of piezoelectric actuators. By decreasing the CPW line width, the S21 losses decrease by almost 1 dB, and S11 stay well below -10 dB in all designs. The structures have been simulated with CST Microwave Studio, and the simulated results demonstrate a total phase shift of more than 180 degrees in all designs with good loss performance.
