The invention relates to an electrically controlled group antenna (1), an antenna element (3) suitable for incorporation in such a group antenna, and antenna module comprising several such antenna elements. According to the invention, the antenna elements comprise a rotationally-symmetrical body (4) tapering towards one end of the body. The rotationally-symmetrical body is provided with a metallic casing surface. Several antenna elements (3) are arranged separately on a common earth plane (2). By means of the invention, a broadband group antenna is achieved that, among other things, is simple in design and is easy to manufacture and repair. |
