Abstract

The invention relates to a radar antenna arrangement (1) for a vehicle (2), comprising at least one vehicle component (3), wherein the radar antenna arrangement (1) comprises a plurality of radar devices (4) which are configured to transmit and/or receive a radar beam (12). The radar devices (4) are arranged on a component surface (5) of the vehicle component (3). The invention provides for the radar antenna arrangement (1) to comprise at least one antenna row (6) for determining an azimuthal angle (10) of the radar beam (12), said antenna row comprising a plurality of the radar devices (4). Directly adjacent radar devices (4) have respective horizontal distances (8) from one another. The radar antenna arrangement (1) comprises at least one antenna column (7) for determining an elevation angle (11) of the radar beam (12), said antenna column comprising a plurality of the radar devices (4). Directly adjacent radar devices (4) have respective vertical distances (9) from one another. The at least one antenna row (6) and the at least one antenna column (7) include an angle α of between 5 degrees and 180 degrees.
