PCT No. PCT/FR95/00226 Sec. 371 Date Oct. 23, 1996 Sec. 102(e) Date Oct. 23, 1996 PCT Filed Feb. 24, 1995 PCT Pub. No. WO96/26554 PCT Pub. Date Aug. 29, 1996A UHF phase shifter including a UHF waveguide having an electrooptical element lying between two elements 3 and 4 made of materials which have permittivity higher than that of the electrooptical element. An electric polarization field is applied for controlling the electrooptical element and a UHF line is inserted into the element. The control of the orientation of the molecules of the electrooptical element allows for a variation of the index of the element as seen by the field of a UHF wave.
