Abstract: A vehicle body for an electrical vehicle includes: side sills, which are coupled to side surfaces of a floor panel, rear side members, front end portions of which overlap rear end portions of the side sills and which are coupled the side surfaces of the floor panel, a battery, which is positioned at a lower portion of the floor panel and is mounted to portions of the side sills in front of the rear side members and to portions at which the side sills overlap the rear side members, and rear extension members having a strength lower than any of the side sills and the rear side members, the rear extension members being connected at front ends thereof to rear ends of the rear side members, and the rear extension members being coupled to the side surfaces of the floor panel.

Abstract: Disclosed is a radar antenna including an antenna body including a first plate and a second plate; a slot radiation part and a slot reception part formed in the first plate; a transmission port and a reception port formed in the second plate; and a waveguide formed by assembling the first and second plates. The slot radiation part includes a first slot radiation part configured to radiate a radio wave in a first detection range, and a second slot radiation part configured to radiate radio waves in a second detection range having a larger width and distance than the first detection range.

Abstract: A vehicle rear structure includes: a pair of side sills mounted on both sides of a floor panel; a pair of rear side members coupled to the pair of side sills, respectively; and a reinforcing member mounted in an inside of each side sill. A front end of each rear side member is coupled to a rear end of each side sill, each rear side member has a front portion aligned with each side sill, respectively, the reinforcing member has a length extending from the inside of each side sill to an inside of the front portion of each rear side member, respectively, a battery housing of a battery assembly is coupled to the pair of side sills and the reinforcing member by a first bolt, and the battery housing of the battery assembly is coupled to the pair of rear side members and the reinforcing member by a second bolt.
