Abstract
A low actuation voltage MEMS shunt capacitive switch has been investigated in this paper. The MEMS switch is a freely moving membrane over co planar waveguide, the beam of the switch is serpentine spring and actuation is achieved by electrostatic mechanism. Actuation voltage achieved is of the order of 4 to 5 volt with down state capacitance of 3.77 pF and spring constant of 1.451 N/m.
