  • High frequency wave radiation system producing a rotating beam defining a predetermined geometrical pattern
    Patent number: 3983561
    Abstract: An electromagnetic wave radiation system includes an array of stationary antenna elements, a multiplicity of phase modulator units coupled to the antenna elements, a source of high frequency energy supplying energy to the antenna array, and modulator driving means activating the same to cause phase displacement and rotation of the beam transmitted by the antenna elements. The antenna may be a discone assembly or an assembly of antenna elements in a circular configuration, and the modulator units may be passive ferrite members located in the aperture of the antenna. The modulator driving units may comprise electromagnets located below the ground plane of the antenna and alternatively or selectively energized by in-phase and phase shifted sine wave voltages.
