1. A microwave antenna arrangement for a motor-vehicle radar system, comprising:
- at least one focusing arrangement focusing electromagnetic waves;
at least one feeder element for at least one of (a) receiving and (b) emitting the electromagnetic waves;
a component support including a cut-out portion allowing a passage of the electromagnetic waves, the component support being situated in a spatial area between the at least one focusing arrangement and the at least one feeder element, the component support being situated substantially transverse to a main beam direction of the microwave antenna arrangement, the component support being spaced from the at least one feeder element and the at least one focusing arrangement; and
electrical components, the component support supporting the electrical components, the electrical components processing signals other than the electromagnetic waves.

Abstract
A microwave antenna arrangement, made up of a focusing element and at least one feeder element, in which arrangement, to attain a small size, at least one component support is arranged in a spatial area between the focusing element and the at least one feeder element, electronic or electrical components being located on the component support. The component support has a cut-out to allow passage of the electronic waves. The component support and the electronic or electrical components are provided for processing signals other than those received or emitted by the at least one feeder element.
