SMALL-SIZED PHASE SHIFTER OF MICROWAVE RANGE Russian patent published in 2014 - IPC H01P1/18 

FIELD: nanotechnologies.

SUBSTANCE: small-sized phase shifter of microwave range includes a microstrip line located on dielectric material and ferroelectric capacitors on a dielectric substrate, which are arranged between its current and earth conductors, and differs by the fact that dielectric material is represented with a diamond plate; the dielectric substrate is made from monocrystalline magnesium oxide with crystalline orientation (100), and as ferroelectric material there used is a film of barium-strontium titanate (Ba_1-xSr_xTiO₃) with thickness of 20±5 nm, where x=0.2±0.01.

EFFECT: reduction of power losses of a microwave signal and increase in upper range of frequencies.
