The micromechanical switch is without doubt the paradigm RF MEMS device. However, a major drawback is that these switches are usually electrostatic in nature and commonly driven by bias voltages in the 40--100 V range. The focus of this investigation was the development of a low actuation voltage RF MEMS switch in the K/Ka-band frequency region. The switch structure is composed of four multi-meander folded suspensions attached to actuation pads over the ground planes of FGCPW lines, resulting in a compact design and low spring design. This allowed for the development of capacitive switches with actuation voltages as low as 6 V (one of the lowest values to date) with switching speeds of approximately 50 musec. Furthermore, top electrodes were added over the actuation pads in order to mitigate the effect of
