    摘要: 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. Preferred embodiments provide a dual mode antenna system in which antenna elements of a first mode are interspersed with antenna elements of a second mode.

    摘要: An antenna operable over a predetermined range of frequency includes a transmission line, a transformer network connected to one end of the transmission line, and at least one ferrite/powder iron network connected to an opposite end of the transformer network. The ferrite/powder iron network changes the effective electrical length of the antenna such that as the frequency of operation changes, the current distribution above and below the network changes in corresponding manner. A second ferrite/powder iron network may be serially positioned with respect to the other network, wherein both function to reduce the current thereabove. Accordingly, as the frequency of operation increases, the electrical height of the antenna decreases. The network also encompasses a way to safely dissipate otherwise destructive heat created by the operation of the antenna system at high radio-frequency power.
