ABSTRACT:
An antenna (10) having an emitter element which is positioned in front of a conductive reflector (13) and has a three-dimensional cast part. The cast part is implemented as conductive and has a closed peripheral structure (11) having alternating constrictions and bulges. The peripheral structure (11) spans an imaginary surface (14) which is intersected by at least two planes of symmetry (15.1, 15.3) of the cast part. At least two fastening elements (12.1, 12.2) are provided, which extend essentially perpendicular to the imaginary surface (14) and support the peripheral structure (11) at two points which lie on one of the planes of symmetry (15.1; 15.3). At the lower ends (16), the fastening elements (12.1, 12.2) are connected to the reflector (13), the fastening elements (12.1, 12.2) also being used for electrical excitation of the emitter element.
