A device and a method for phase shifting on at least one single-layer or multilayer substrate, in particular a substrate also having at least one metallic layer, to which is applied at least one planar line, in particular in the form of a strip line or in the form of a symmetrical or asymmetrical coplanar line or in the form of a microstrip line or in the form of a slot line or in the form of a coplanar dual-strip line so that the advantages of a slow-wave structure may also be used in mechanically controllable phase shifters, the phase shift is adjustable by varying the effective dielectric constant, in particular the propagation coefficient, of the line by providing line sections going out from the line, in particular no-load line sections and/or in particular line sections short-circuited at their particular ends and/or stubs going out from the line and/or alternating line segments of a high impedance and line segments of a low impedance and/or discrete elements such as inductors, capacitors or inductive and/or capacitive line bridges and/or in particular discrete serial and/or parallel reactances and/or in particular discrete serial and/or parallel susceptances and/or in particular effective line quantities per unit length such as capacitance per unit length, e.g., transverse capacitance per unit length, or inductance per unit length, e.g., longitudinal inductance per unit length.
