The present invention relates to a loop antenna for a vehicle. The loop antenna for vehicles includes: a watertight plate attached on a loop panel and having a plurality of watertight ribs restricting inflow of liquid in the upper surface; a base provided on the upper surface of the watertight plate and having a screw portion which penetrates the loop panel and the watertight plate, is protruded inside the loop panel, and disposed on the lower surface thereof; a case attached to the upper surface of the base; and a ground nut fixing the watertight plate and the base to the loop panel by being coupled to the screw portion, and having a plurality of teeth at the upper end thereof making contact with the loop panel, wherein the teeth are formed in a right triangular shape. Since right triangular shaped teeth perpendicular to the loop panel are formed in the ground nut keeping adhesion between the loop panel and the antenna, the antenna provides effects of preventing the ground nut from reverse rotation due to external force, enhancing coupling force between a vehicle loop antenna and the loop panel by the earth nut, and preventing the liquid from flowing into the interior of the vehicle through the antenna. |
