摘要

The device has a radiator element with as three-dimensional cast part arranged in front of a conducting reflector (13). The cast part has at least two planes of symmetry (15.1,15.3), is conducting and has a closed peripheral structure (11) with alternating constrictions and expansions and at least two attachment elements (12.1,12.2) connected to the reflector. At least one attachment element is used to electrically stimulate the radiator element. AN Independent claim is also included for the following: (a) a group antenna with several inventive antennas.
