TLDR
In this paper, a lineal polarized wave has been shifted in phase and rotated in polarization in accordance with a cascade connection of a NRCP, Faraday rotator and a RNRCP.Abstract:
Each antenna of the phased array is supplied a lineal polarized wave which has been shifted in phase and rotated in polarization in accordance with a cascade connection of a NRCP, Faraday rotator and a RNRCP. The control windings of the Faraday rotator and the rotating polarizer determine the amount of phase shift and rotation of the polarization of the propagating wave.read more

Waveguide polarizer having conductive and dielectric loading slabs to alter polarization of waves
TL;DR: In this paper, a waveguide polarizer is proposed to alter the propagation modes of an incident wave to produce elliptical or circular polarization, and the phase shift is produced by the simultaneous use of dimensional perturbation and dielectric loading distributed along a wave-guide section.
Patent
Adjustable-phase-power divider apparatus
TL;DR: A phase shifter as mentioned in this paper is a phase shifting device which imposes a desired phase shift on an electromagnetic wave traveling through a waveguide, and divides the power in an output waveguide into two parts.

Monolithic reciprocal latching ferrite phase shifter
TL;DR: In this article, a monolithic phase shifter assembly is constructed from a single slab of ferrite material, such that the phase shifters comprises a single monolithic ferrite structure, providing the overall functional characteristics of the phase shift through an integrated combination of individual portions of the monolithic structure.

Unidirectional phase shifter
TL;DR: In this paper, the phase shifter consists of two ferrite phasor sections arranged such that the phase changes of the two sections add for one direction of signal flow and cancel for the other.
