  • Dual space fed parallel plate lens antenna beamforming system
    Patent number: 4595926
    Abstract: A beamforming system for a linear phased array antenna system which can be sed in a monopulse transceiver, comprising a pair of series connected parallel plate constrained unfocused lenses which provide a suitable amplitude taper for the linear array to yield a low sidelobe radiation pattern. Digital phase shifters are used for beam steering purposes and the unfocused lenses decorrelate the quantization errors caused by the use of such phase shifters.
