N2 - In this paper, a novel RF-MEMS phase shifter based on a rectangle bridge-like coplanar waveguide (BCPW) structure is proposed. The signal line of the coplanar waveguide (CPW) has symmetrical saw-shaped structures under the MEMS bridges above which covers the BCPW bridge. The CST software is used for the modeling, simulation and optimization the model of pahse shifter from 30 to 40GHz. Simulation and optimization results show that the proposed design with a 35GHz central resonant frequency has a return loss less than -10dB within about 2GHz bandwidth range and for each RF MEMS switch-type bridge, as high as 75 degrees phase shift is realized. Compared with MEMS phase shifters without a BCPW bridge, Sn performance can be improved by up to 10dB, and interference among the adjacent components can be decreased.
