Polarized antenna array
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.
