    Patent number: 6198434
    Abstract: Systems and methods for providing antenna beams having reduced grating and side lobes when steered off of the antenna broadside are disclosed. According to the present invention an arrangement of antenna elements suitable for use in generating antenna beams steered at greater angles off of the antenna broadside is utilized with a beam feed network consistent with the antenna beams being steered at the greater angles and reduced antenna element spacing to provide the reduced grating and side lobes. A preferred embodiment utilizes a 2n+1 Butler matrix coupled to 2n+1 antenna columns spaced according to the present invention to provide 2n antenna beams.
