MICROSTRIP FIXED UHF PHASE SHIFTER Russian patent published in 2023 - IPC H01P1/185 

FIELD: radio engineering.

SUBSTANCE: microstrip fixed microwave phase shifter consists of reference (RC) and phase-shifting (FC) channels. The phase-shifting channel is formed by a cascade connection of three segments of a homogeneous single microstrip transmission line with different lengths and wave impedances. A short-circuited loop is connected in parallel to the central segment of the PC formed by a cascade connection of three segments of a homogeneous transmission line with different lengths and wave impedances. The wave impedances of the segments satisfy the following relations: Z₁<Z₀, Z₁<Z₂, Z₀≈Z₂, Z₃<Z₄<Z₅; or Z₀>Z₁>Z₂, Z₃>Z₄, Z₃ = Z₅.

EFFECT: creation of a broadband microstrip fixed microwave phase shifter having small overall dimensions with improved frequency characteristics.
