Abstract

The invention discloses a vehicle-mounted millimeter-wave radar antenna, a radar and a vehicle, and the vehicle-mounted millimeter-wave radar antenna comprises a 1-to-n power dividing feed network, and n is a natural number greater than 2; n single-column antenna arrays, each single-column antenna array is correspondingly connected with one output end of the power division feed network, each single-column antenna array is formed by connecting k antenna radiation units in series through a microstrip line, and k is a natural number greater than 3; and the upper bottom surface of the trapezoidal reflection matching section is connected with the antenna radiation unit at the tail end of the single-row antenna array, and the lower bottom surface of the trapezoidal reflection matching section is connected with the microstrip line. By adding an antenna design structure of a trapezoidal reflection matching section in front of the last antenna radiation unit, the sidelobe level of a directional diagram can be integrally reduced by about 2dB, the antenna directional diagram can be effectively optimized, the signal-to-noise ratio of a radar system can be improved, and the anti-interference capability of a millimeter wave radar system can be improved.

Description

technical field [0001] The invention relates to the technical field of vehicle antennas, in particular to a vehicle millimeter wave radar antenna, a radar and a vehicle.
