Abstract

The invention belongs to the technical field of antennas, and particularly relates to a Ka-band high-gain substrate-integrated waveguide ripple antenna and system. The antenna comprises a dielectric layer, a first metal layer and a second metal layer, wherein the first metal layer is attached onto an upper surface of the dielectric layer, the second metal layer is attached onto a lower surface ofthe dielectric layer, a through hole is formed in each of the first metal layer and the second metal layer, the shapes of the through holes are same, the vertical positions of the three through holesare corresponding to each other, a plurality of hollow concentric rings are arranged on the first metal layer, a metal via hole structure is arranged on the dielectric layer, and the first metal layercommunicates with the second metal layer by the metal via hole structure. The invention also provides an antenna system. The antenna system comprises a matched waveguide, a standard rectangular waveguide and the antenna, wherein the matched waveguide is connected with the second metal layer, and the standard rectangular waveguide is connected with the matched waveguide. The antenna has the advantages of high gain, wide bandwidth, narrow E-surface and H-surface main lobe beam width, low cross polarization and the like.
