  • Apparatus for processing radio frequency signals
    Patent number: 11456514
    Abstract: Apparatus for processing radio frequency, RF, signals, wherein said apparatus comprises at least a first transmission line and a second transmission line, and an electrically conductive element that is capacitively coupled with said first transmission line and said second transmission line and that is translationally movably arranged with respect to at least one of said first transmission line and said second transmission line.
    Type: Grant

  • Polarized antenna array
    Patent number: 11233340
    Abstract: A polarized antenna array is provided that includes multiple polarized antenna elements. The polarized antenna array has a polarization vector defining a co-polarization direction and a cross-polarization direction. The multiple polarized antenna elements include a first sub-set of polarized antenna elements that collectively have a first polarization vector and a second sub-set of polarized antenna elements that collectively have a second polarization vector. Application of a controlled phase difference between the first sub-set of polarized antenna elements and the second sub-set of polarized antenna elements causes constructive combination of the first polarization vector and second polarization vector in the co-polarization direction and destructive combination of the first polarization vector and the second polarization vector in the cross-polarization direction.
