Abstract

A phase shift device includes a planar transmission line that is formed by a signal electrode and a ground electrode which are separated by a dielectric substance, whereby the signal electrode of the planar transmission line is divided into several pieces and includes overlapping areas of adjacent pieces that are filled with a tunable liquid crystal material, thereby forming a dielectric tunable component (varactor) with a metal-insulator-metal type capacitor. The several pieces of the signal electrode are arranged at two or more different distance levels with respect to the ground electrode. The tunable liquid crystal material is arranged as a continuous layer between several pieces of the signal electrode that are arranged at two different distance levels.
