Abstract: A radio signal polarization switching arrangement is responsive to linearly polarized radio signals, such as television signals from a satellite. The switching arrangement which is capable of selecting signals having either one of predetermined states of linear polarization comprises a dielectric support block which supports a ferrite rod axially in a circular waveguide. A metal or metallized layer is deposited on an external surface of the support block and an energizing coil is wound around the layer in axial alignment with the rod. The support block has a stepped configuration at opposite ends in order to compensate for the loading effect of the ferrite rod on the waveguide.

Abstract: A phase-shifter apparatus 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. The phase shifter apparatus includes a quarter-wave plate for changing the polarization of the linearly polarized wave to a circularly polarized wave, a rod of ferromagnetic material with a magnetic field for imposing a desired phase shift on the circularly polarized wave traveling through the rod, a quarter-wave plate for converting the circularly polarized wave to a linearly polarized wave, and a septum polarizer in the output wave guide for dividing the power. The output waveguide has the power divided between two ports, and independent phase shifts are imposed on the electromagnetic waves of each port.

Abstract: Method and apparatus for reducing the loss in a microwave phase shifter by the use of circular TEn1 modes where n is greater than unity. The apparatus comprises: a ferrite filled circular waveguide having a diameter sufficiently large to propagate TE21, TE31 or higher modes; a solenoid adapted to be operated so as to provide a Faraday rotation on the electromagnetic fields propagated in the ferrite filled waveguide; and a pair of circular TE mode transducers or converters respectively coupled to each side of the circular waveguide where for example a circular TE11 mode rf input signal is fed into the first mode converter. The rf is transformed into a selected higher TEn1 mode where n>1 and where it is fed through the ferrite filled circular waveguide. A predetermined Faraday rotation of the TEn1 wave takes place with the second mode converter then transforming the TEn1 signal back to the input mode which then comprises an rf output shifted in phase with respect to the rf input, the phase shifted in phase with respect to the rf input, the phase shift being effected through the higher mode rf signal propagating in the ferrite filled circular waveguide.

Abstract: A millimeter-wave phase shifter for use at high millimeter-wave frequencies is disclosed. The phase shifter employs continuous aperture ferrite and corrugated horns to make a reciprocal phase shifter in the frequency range of interest. Applied linearly polarized energy is expanded in cross-section by means of a first corrugated horn. The expanded energy is focused by a first lens, circularly polarized and applied to a ferrite phase shifting section. The phase shift applied to the energy is controlled by means of phase control circuitry and a yoke and coil arrangement. The phase-shifted energy is then converted to linearly polarized energy by a second circular polarizer focused by a second lens and contracted in cross-section by a corrugated horn. The use of the corrugated horns, polarizers, lenses and ferrite phase shifting components allows a much larger device to be fabricated and hence physical tolerances are reduced by an order of magnitude for the frequency range of interest. In addition, both the efficiency and power handling capability are greatly improved. Both reciprocal and nonreciprocal phase shifters are disclosed.

Abstract: Disclosed is an antenna feed system for use in satellite communication systems and the like, comprising a horn with a rectangular aperture and a waveguide connected thereto. The assembly formed by the waveguide and horn is constructed from two parts secured together so that the junction lies in the longitudinal symmetry plane parallel to the electric field of the TE.sub.01 mode and is mounted for rotation about the longitudinal axis of the waveguide. The feed system further comprises a polarization converter mounted in front of the horn for rotation about the extention of the longitudinal axis of the waveguide. The converter is constructed from a plurality of layers of supporting material each provided with a conductor which forms in one direction a mainly inductive load and in a direction which is perpendicular thereto a mainly capacitive load.
