Disclosed is a radar antenna. The disclosed antenna comprises: a dielectric substrate; a feed line for feeding an RF signal, wherein the feed line is formed on the dielectric substrate and has a line shape; a plurality of radiators each of which is vertically coupled to the feed line, and each of which has a bent structure comprising: a horizontal portion, and a vertical portion; a matching element coupled to one end of the feed line so as to adjust an impedance matching; and a grounding surface formed at the lower surface of the dielectric substrate. The length of the horizontal portion and the length of the vertical portion are set on the basis of the angle of the polarized wave of an RF signal to be radiated. The disclosed antenna may be manufactured to have a simplified and miniaturized structure.
