ABSTRACT:
Provided is a micro-electromechanical systems switch for controlling signal delivery in a high frequency band wireless communication and a radio frequency (RF) system and, comprising: a substrate; a signal line formed on the substrate and having a predetermined opening portion; at least one supporting frame each formed on the substrate at both sides of the signal line; a ground line formed on the substrate between the supporting frame and the signal line; a moving plate fixed to the supporting frame at both sides thereof, the moving plate being movable upward and downward; a switching unit positioned on the moving plate, the switching unit comprising contact means for connecting the opened signal line; and a supporting layer for supporting the moving plate and the switching unit, wherein the supporting layer comprises a support protrusion portion for maintaining a distance from the substrate.
