Abstract
Bei einer Reflektorantenne zur Bündelung von Radarwellen für Abstandssensoren, insbesondere Fernsicht-Radarsensoren für ein Kraftfahrzeug, mit einem Hauptreflektor und ggf. einem oder mereren Subreflektoren, weist der Hauptreflektor und/oder ggf. der mindestens eine Subreflektor zumindest eine Störstelle auf, die eine Verbreiterung eines einzelnen Antennenstrahls, vorzugsweise mehrerer Antennenstrahlen, und/oder einer Verringerung einer Nebenkeule eines Antennenstrahls, vorzugsweise mehrerer Antennenstrahlen, bewirken.
