description The invention discloses a wide-beam 77GHz millimeter wave vehicle-borne radar antenna, which comprises an upper dielectric substrate, a middle dielectric substrate and a lower dielectric substrate arranged in sequence. A metal ground is arranged on one side of the middle dielectric substrate corresponding to the lower dielectric substrate, and exciting radiation units are arranged on the other side. Parasitic radiation units are arranged at positions corresponding to the exciting radiation units on the upper dielectric substrate. A feeding unit is arranged on one side of the lower dielectric substrate away from the middle dielectric substrate, and the feeding unit is used to feed electromagnetic wave signals into the exciting radiation units and the parasitic radiation units. A U-shaped through slot is arranged in one side of a radiation patch of each exciting radiation unit, metalized through holes are added around each U-shaped through slot, and a metal probe is arranged on the otherside of each radiation p
