Abstract (en)
[origin: EP1077508A2] The antenna has drivable radiating antenna elements mounted on a base body. The base body (G) is in the form of a truncated cylinder (Z) with a polyhedron (K) mounted on it, whereby each surface of the polyhedron has an antenna element (E1,E2,E5). An Independent claim is also included for a method of operating an antenna.
