Abstract

The present invention suggests a radar antenna in which a rounded edge surface is formed in a receiving hole formed by an antenna body and a shielding frame. The suggested radar antenna comprises: an antenna body having a plurality of first slots formed on a first surface thereof; and a shielding frame through which reception holes for receiving the plurality of first slots are formed, the reception holes being arranged on the first surface of the antenna body to receive the plurality of first slots, wherein a corner at which the inner wall surface of the shielding frame is connected to the first surface of the antenna body is formed to have a round structure.

Claims4

Dependent claims

A radar antenna comprising:

an antenna body in which a plurality of first slots is formed in a first surface of the antenna body;
a shielding frame having a flat shape with a predetermined thickness and formed to protrude from the first surface of the antenna body,
wherein the shielding frame includes an accommodation hole penetrating the shielding frame in an up-and-down direction and accommodating the plurality of first slots,
wherein an edge at which an inner wall surface of the shielding frame and the first surface of the antenna body are connected is formed to have a concave round structure, and
a plated metal layer formed in the accommodation hole,
wherein the plated metal layer is disposed along the concave round structure formed at the connection between the inner wall surface of the shielding frame and the first surface of the antenna body.
