A MEMS switch and method of fabrication comprises a RF transmission line; a RF beam structure comprising a RF conductor; a cantilevered piezoelectric actuator coupled to the RF beam structure; a plurality of air bridges connected to the cantilevered piezoelectric actuator; and a plurality of contact dimples on the pair on the RF beam structure. The RF transmission line comprises a pair of co-planar waveguide ground planes flanking the RF conductor; and a plurality of ground straps, wherein the RF transmission line is operable to provide a path along which RF signals propagate. The cantilevered piezoelectric actuator comprises a dielectric layer connected to the RF beam structure; a bottom electrode connected to the dielectric layer; a top electrode; and a piezoelectric layer in between the top and bottom electrodes, wherein the top electrode is offset from an edge of the piezoelectric layer and the bottom electrode.
