DISCRETE TRANSMISSION PHASE SHIFTER Russian patent published in 2013 - IPC H01P1/00 

FIELD: radio engineering, communication.

SUBSTANCE: in a discrete transmission phase shifter, having a waveguide along the axis of which, in the cross-section, there are dielectric plates with asymmetrical planar coupling loops and control electrodes and p-i-n diodes connected thereto, the waveguide has a flat-topped cross-section, and the dielectric plates with planar coupling loops are located between a protrusion and the side wall of the flat-topped waveguide, and the p-i-n diodes are connected to the ends of each loop.

EFFECT: smaller cross dimension of the phase shifter and wider operating bandwidth of the phase shifter.
