1. A method for manufacturing a radar antenna, comprising:
manufacturing a plate-shaped first plate and a plate-shaped second plate, wherein the plate-shaped first plate includes a first coupling protrusion and a second coupling protrusion, wherein the second coupling protrusion protrudes higher than the first coupling protrusion, wherein a nut is in-molded in the second coupling protrusion, wherein the plate-shaped second plate includes a first coupling groove and a second coupling groove, wherein the first coupling groove has a depth corresponding to a height of the first coupling protrusion and is configured to receive the first coupling protrusion, wherein the second coupling groove has a depth corresponding a height of the second coupling protrusion and is configured to receive the second coupling protrusion, and wherein a nut is in-molded in the first coupling groove,
forming a shielding layer on surfaces of the first plate and surfaces of the second plate;
curing the first plate and the second plate on which the shielding layer is formed through at least one of a compression process and a thermal aging process; and
assembling the first plate and the second plate cured in the curing.
