DIGITAL PHASE SHIFTER WITH SUPER-WIDE BANDWIDTH Russian patent published in 2018 - IPC H01P1/18 

FIELD: antenna equipment.

SUBSTANCE: invention relates to the antenna equipment. Phase shifter comprises coupler, first and second impedance networks. At that, the coupler is cascaded by the spiral inductors communication units. Each stage of the spiral inductors communication unit includes connected to each other first and second spiral inductors. Spiral inductors communication units multistage cascade is made in the form of the first spiral inductor each stage in-series connection and the second spiral inductor each stage in-series connection. Cascaded into the coupler and located from the outside the spiral inductors communication unit first stage first spiral inductor one end is the coupler input end, and also serves as the phase shifter input end, and located from the outside second spiral inductor one end is the connected to the first impedance network coupler connecting end. At the spiral inductors communication unit last stage first spiral inductor one end in located from the outside coupler is the connected to the second impedance network coupler transmission port, located from the outside second spiral inductor one end is the coupler isolated end and also serves as the phase shifter output end. Spiral inductors each communication unit microstrip line communication interval or bandwidth in the coupler is gradually reducing from the outside to the inside.

EFFECT: technical result consists in increase in the structure compactness and the occupied space reduction.
