Abstract (en)
[origin: US4575728A] A vertical dipole array (2, 3 to 2(n), 3(n)) is formed on a substrate (1) using stripline techniques. The dipoles are supplied with RF energy from a feed system consisting of stripline conductors (4, 4', 5, 6, 7, 7', 9, 12). By a parasitic compensating radiator (11) provided opposite these conductors on the same side of the substrate, the influence of the conductors on the radiation pattern of the dipoles is largely compensated for. The conductors of the feed system are arranged so that a combination of a parallel feed and an equal line length series feed (or, if the radiation pattern is to be raised, a series feed with suitably chosen line lengths) is obtained.
