3 bit 90/spl deg/ millimeter phase shifter using microfluidic technology

Addressing systems that require broadband devices for high data rate communication or high resolution radar, we develop the concept of a millimeter phase shifter that combines micro strip or coplanar wave guide and microfluidic facilities. To illustrate this approach we built from a simple analytical equation the main steps of the design of a 3 bits 90° 60GHz broadband (3GHz) pbase shifter. Preliminary results performed by a 3D elech.omagnetic simulator are then presented.
