Abstract:
1. An RF MEMS switch, comprising: a cap substrate; a bottom substrate having a certain gap from the cap substrate; a signal transmission line constituted with a single signal transmission line, and disposed at the cap substrate; a connection line disposed at the cap substrate, and connected with the signal transmission line; and an on/off means disposed at the bottom substrate, and turning on/off the signal transmission line for transmitting signal, wherein the on/off means comprises; one or more piezoelectric capacitors disposed at the bottom substrate, and actuated with a piezoelectric characteristic by receiving an external power; and a capacitor contact electrode connected with a first metal layer protruding from the piezoelectric capacitor, wherein a ground line is formed adjacent to the signal transmission line and electrically connected to the signal transmission line by the connection line.
