Claim Text:
1. An antenna system comprising: an antenna array comprising: a dielectric substrate of a rectangle shape; a plurality of radiation patches arranged at intervals in the length direction of the dielectric substrate and formed on the top surface of the dielectric substrate; and a plurality of coupling patches arranged in correspondence to the plurality of radiation patches, each of which formed on the top surface of the dielectric substrate and extending from a side of the dielectric substrate to a position from a corresponding radiation patch by a distance, and a waveguide horn array comprising: a rectangular metal plate which is processed to have a cross section comprised of a plurality of rectangular holes arranged in the length direction of the rectangular metal plate, the lower part of each hole being formed as a rectangular waveguide, and the upper part of each hole being formed as a horn, and a groove extending in the direction along which the plurality of holes are arranged and having a predetermined depth, which is formed at two sides of the holes on the top surface of the rectangular metal plate, wherein the respective rectangular waveguides of the waveguide horn array have a same size with the radiation patches, and each of the rectangular waveguides is coupled to the corresponding radiation patch.
