Title:
RF MEMS SWITCH USING SHAPE CHANGE OF FINE LIQUID METAL DROPLET
Document Type and Number:
WIPO Patent Application WO/2011/059235
Kind Code:
A2
Abstract:
The present invention provides an RF MEMS switch using a fine liquid metal droplet, which can quickly be operated and strong to impact and movements. According to one embodiment of the present invention, the RF MEMS switch using the fine liquid metal droplet comprises: a first layer member which includes a signal transmission line; a second layer member which is disposed on the first layer member, forms a chamber in order to induce a shape change of the fine liquid metal droplet by coping with the signal transmission line, and forms a through hole on one side of the chamber in order to contact or non-contact the signal transmission line with the fine liquid metal droplet of which shape is changed in the chamber; an operating member which is disposed on the second layer member, and is positioned on the open side of the chamber in order to provide the power of the shape change to the fine liquid metal droplet through the open side of the chamber; and a third layer member which sets the position of the operating member, and is coupled with the first layer member and the second layer member.
