PHASE SHIFTER Russian patent published in 2008 - IPC H01P1/185 

FIELD: physics.

SUBSTANCE: invention concerns UHF technology and is intended for UHF signal phase control. Objective is achieved by supplying phase shifter with dielectric substrate, one side of which carries current-carrying conductor consisting of regular strip conductor sections of various length and width, which function as half-wave resonators at work frequencies and serve to form band-pass property. Other side of substrate carries plated coating. Screening conductor is positioned at a definite height from current-carrying conductor.

EFFECT: adjustable phase shift in sentimetre band with value stability under effect of weather factors and in absence of control voltage.
