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.

Radar antenna

An antenna package having a cavity structure is provided, wherein a cavity substrate having an accommodation portion formed therethrough is disposed on one surface of an antenna substrate having a signal processing element formed thereon, so as to prevent occurrence of deformation and breakage thereof in the process of mounting the antenna package. The provided antenna package having the cavity structure comprises: an antenna substrate, on the upper surface of which multiple radiation patches are formed and on the lower surface of which multiple signal processing elements are formed; and a cavity substrate which has an accommodation portion formed therethrough to receive the multiple signal processing elements and is disposed on the lower surface of the antenna substrate.
