Electrically controlled broadband group antenna, antenna element suitable for incorporation in such a group antenna, and antenna module comprising several antenna elements

摘要

An electrically controlled group antenna including an antenna element suitable for incorporation in such a group antenna and an antenna module including several such antenna elements. The antenna elements include a rotationally-symmetrical body tapering towards one end of the body. The rotationally-symmetrical body is provided with a metallic casing surface. Several antenna elements are arranged separately on a common earth plane. A broadband group antenna is achieved that, among other things, is simple in design and is easy to manufacture and repair.
