1. An electrically controlled broadband group antenna, comprising:
a plurality of antenna radiating elements arranged in a common plane, each antenna radiating element comprising a body arranged on a ground plane that is common to several of the antenna radiating elements, each body comprising a rotationally-symmetrical surface having an axis of rotation substantially perpendicular to the ground plane, the surface of each body having a shape that tapers toward the axis of rotation with increasing distance from the ground plane, the surface of each body being entirely covered with a metallic casing; and
a feeder unit operatively connected to the antenna radiating elements.
