  • Patent number: 9178285
    Abstract: A phase shift device includes an input quadrature junction for receiving an input EM signal and extracting a first electromagnetic (EM) signal, a second EM signal, a third EM signal, and a fourth EM signal from the input EM signal. Four waveguide arms are operatively connected to the input quadrature junction for respectively conveying the first, second, third, and fourth EM signals therethrough. At least two of the waveguide arms shift the phase of EM signal conveyed therethrough such that two of the first, second, third, and fourth EM signals are phase shifted with respect to the other two of the first, second, third, and fourth EM signals. An output quadrature junction is operatively connected to the waveguide arms for combining the first, second, third, and fourth EM signals. Thus, polarization adjustment may be achieved through rotation of the phase shift device.
