  • Multiple polarization antenna element
    Patent number: 4063248
    Abstract: A multiple polarization antenna element comprises a combination of a waveguide radiator and a dipole radiator disposed across the waveguide aperture. The dipole radiator is orientated to radiate a polarization perpendicular to the radiation from the waveguide aperture. Independent means are provided for supplying wave energy signals to the waveguide and dipole radiators. The arrangement of the elements is such that both polarizations are radiated from substantially the same phase center.
