An electrostatic RF-MEMS switch with low coefficient of elasticity was designed and implemented in the X-band switched-line phase shifter.By the simulation and optimization with the finite element methods in both mechanical and electrical properties of the multi-anchored beams
achieved the actuation voltage is 36.5 V and the elasticity coefficient is 17.63 N/m.In the operation frequency of 10 GHz
the insertion loss of the phase shifter is limited below 9 dB.
